Subject: reset: Remove addr parameter from reset_cpu()

Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

Subject: sandbox: Add os_realloc()

We provide os_malloc() and os_free() but not os_realloc(). Add this,
following the usual semantics. Also update os_malloc() to behave correctly
when passed a zero size.

Subject: sandbox: Avoid using malloc() for system state

This state is not accessible to the running U-Boot but at present it is
allocated in the emulated SDRAM. This doesn't seem very useful. Adjust
it to allocate from the OS instead.

The RAM buffer is currently not freed, but should be, so add that into
state_uninit(). Update the comment for os_free() to indicate that NULL is
a valid parameter value.

Note that the strdup() in spl_board_load_image() is changed as well, since
strdup() allocates memory in the RAM buffer.

Subject: tpm: Add an API that can support v1.2 and v2

There are two different TPM standards. U-Boot supports both but each has
its own set of functions. We really need a single TPM API that can call
one or the other. This is not always possible as there are some
differences between the two standards, but it is mostly possible.

Add an API to handle this. So far it is not plumbed into the build and
only supports TPMv1.

From d6a885f0878043d572bfd85a423e4a6bb6073178 Mon Sep 17 00:00:00 2001
From: Simon Glass <sjg@chromium.org>
Date: Sat, 6 Feb 2021 14:23:36 -0700
Subject: tpm: Switch TPMv1 over to use the new API

Take over the plain 'tpm_...' functions for use by the new TPM API. Rename
all the TPMv1 functions so they are called from the API.

Update the TPMv1 functions so that they are called from the API. Change
existing users to use the tpm1_ prefix so they don't need to go through
the API, which might introduce uncertainty.

Subject: tpm: Allow disabling platform hierarchy with TPM2

With TPM2 we don't actually lock the TPM once verified boot is finished.
Instead we disable the platform hierarchy which serves the same purpose.
Add an implementation of this so we can safely boot into the kernel.

Subject: video: sunxi_display: Convert to DM_VIDEO

DM_VIDEO migration deadline is already expired, but around
80 Allwinner boards are still using video in a legacy way:

===================== WARNING ======================
This board does not use CONFIG_DM_VIDEO Please update
the board to use CONFIG_DM_VIDEO before the v2019.07 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/migration.rst for more info.
====================================================

Convert the legacy video driver over to the DM_VIDEO framework. This is
a minimal conversion: it doesn't use the DT for finding its resources,
nor does it use DM clocks or DM devices for the outputs (LCD, HDMI, CVBS).

Tested in Bananapi M1+ Plus 1920x1200 HDMI out. (Jagan)

Subject: dm: gpio: Rename set_dir_flags() method to update_flags()

The current method is a misnomer since it is also used (e.g. by stm32) to
update pull settings and open source/open drain.

Rename it and expand the documentation to cover a few more details.

Subject: dm: gpio: Rename get_dir_flags() method to get_flags()

It is more useful to be able to read all the flags, not just the direction
ones. In fact this is what the STM32 driver does. Update the method name
to reflect this.

Tweak the docs a little and use 'flagsp' as the return argument, as is
common in driver model, to indicate it returns a value.

Subject: gpio: Rename dm_gpio_get_dir_flags() to dm_gpio_get_flags()

This function can be used to get any flags, not just direction flags.
Rename it to avoid confusion.

Subject: dm: gpio: Add a way to update flags

It is convenient to be able to adjust some of the flags for a GPIO while
leaving others alone. Add a function for this.

Update dm_gpio_set_dir_flags() to make use of this.

Also update dm_gpio_set_value() to use this also, since this allows the
open-drain / open-source features to be implemented directly in the
driver, rather than using the uclass workaround.

Update the sandbox tests accordingly. This involves a lot of changes to
dm_test_gpio_opendrain_opensource() since we no-longer have the direciion
being reported differently depending on the open drain/open source flags.

Also update the STM32 drivers to let the uclass handle the active low/high
logic.

Drop the GPIOD_FLAGS_OUTPUT() macro which is no-longer used.

Subject: gpio: Replace direction_input() and direction_output()

The new update_flags() method is more flexible since it allows the
driver to see the full flags all at once. Use that in preference to these
two functions. Add comments to that effect.

Subject: gpio: Add a way to read 3-way strapping pins

Using the internal vs. external pull resistors it is possible to get
27 different combinations from 3 strapping pins. Add an implementation
of this.

This involves updating the sandbox GPIO driver to model external and
(weaker) internal pull resistors. The get_value() method now takes account
of what is driving a pin:

   sandbox: GPIOD_EXT_DRIVEN - in which case GPIO_EXT_HIGH provides the
          value
   outside source - in which case GPIO_EXT_PULL_UP/DOWN indicates the
          external state and we work the final state using those flags and
          the internal GPIOD_PULL_UP/DOWN flags

Of course the outside source does not really exist in sandbox. We are just
modelling it for test purpose.

Subject: test: Rename test-main.c to test-dm.c

This is the main test function for driver model but not for other tests.
Rename the file and the function so this is clear.

Date: Sun, 7 Mar 2021 17:34:47 -0700
Subject: test: Add an overall test runner

Add a new test runner that will eventually be able to run any test. For
now, have it run the 'command' unit tests, so that the functionality in
cmd_ut_category() moves into it.

Subject: test: Call test_pre/post_run() from driver model tests

Ultimately we want to get rid of the special driver model test init and
use test_pre_run() and test_post_run() for all tests. As a first step,
use those function to handle console recording.

For now we need a special case for setting uts->start, but that wil go
away once all init is in one place.

Subject: test: Handle driver model reinit in test_pre_run()

For driver model tests we want to reinit the data structures so that
everything is in a known state before the test runs. This avoids one test
changing something that breaks a subsequent tests.

Move the call for this into test_pre_run().

Subject: test: Drop struct dm_test_state

Driver model is a core part of U-Boot. We don't really need to have a
separate test structure for the driver model tests and it makes it harder
to write a test if you have to think about which type of test it is.

Subsume the fields from struct dm_test_state into struct unit_test_state
and delete the former.

Subject: test: Use ut_run_test() to run driver model tests

Instead of having a separate function for running driver model tests, use
the common one. Make the pre/post-run functions private since we don't
need these outside of test-main.c

Subject: test: Add ut_run_test_live_flat() to run tests twice

Driver model tests are generally run twice, once with livetree enable and
again with it disabled. Add a function to handle this and call it from the
driver model test runner.

Make ut_run_test() private since it is not used outside test-main.c now.

Subject: test: Use a local variable for test state

At present we use a global test state for all driver-model tests. Make use
of a local struct like we do with the other tests.

To make this work, add functions to get and set this state. When a test
starts, the state is set (so it can be used in the test). When a test
finishes, the state is unset, so it cannot be used by mistake.

Subject: test: Add a macros for finding tests in linker_lists

At present we use the linker list directly. This is not very friendly, so
add a helpful macro instead. This will also allow us to change the naming
later without updating this code.

Subject: test: Rename all linker lists to have a ut_ prefix

At present each test suite has its own portion of the linker_list section
of the image, but other lists are interspersed. This makes it hard to
enumerate all the available tests without knowing the suites that each one
is in.

Place all tests together in a single contiguous list by giving them
common prefix not used elsewhere in U-Boot. This makes it possible to find
the start and end of all tests.

Subject: sandbox: Update os_find_u_boot() to find the .img file

At present this function can only locate the u-boot ELF file. For SPL it
is handy to be able to locate u-boot.img since this is what would normally
be loaded by SPL.

Add another argument to allow this to be selected.

While we are here, update the function to load SPL when running in TPL,
since that is the next stage.

Subject: spl: test: Add a test for spl_load_simple_fit()

As an example of an SPL test, add a new test for loading a FIT within
SPL. This runs on sandbox_spl. For this to work, the text base is adjusted
so that there is plenty of space available.

While we are here, document struct spl_load_info properly, since this is
currently ambiguous.

This test only verifies the logic path. It does not actually check that
the image is loaded correctly. It is not possible for sandbox's SPL to
actually run u-boot.img since it currently includes u-boot.bin rather than
u-boot. Further work could expand the test in that direction.

The need for this was noted at:

Subject: log: Set up a flag byte for log records

At present only a single flag (force_debug) is used in log records. Before
adding more, convert this into a bitfield, so more can be added without
using more space.

To avoid expanding the log_record struct itself (which some drivers may
wish to store in memory) reduce the line-number field to 16 bits. This
provides for up to 64K lines which should be enough for anyone.

Subject: log: Handle line continuation

When multiple log() calls are used which don't end in newline, the
log prefix is prepended multiple times in the same line. This makes the
output look strange.

Fix this by detecting when the previous log record did not end in newline.
In that case, setting a flag.

Drop the unused BUFFSIZE in the test while we are here.

As an example implementation, update log_console to check the flag and
produce the expected output.

Subject: log: Add return-checking macros for 0 being success

The existing log_ret() and log_msg_ret() macros consider an error to be
less than zero. But some function may return a positive number to indicate
a different kind of failure. Add macros to check for that also.

 can make it easier to trace errors that are generated deep in the call stack.

Subject: common: SCP03 control (enable and provision of keys)

This Trusted Application allows enabling SCP03 as well as provisioning
the keys on TEE controlled secure element (ie, NXP SE050).

All the information flowing on buses (ie I2C) between the processor
and the secure element must be encrypted. Secure elements are
pre-provisioned with a set of keys known to the user so that the
secure channel protocol (encryption) can be enforced on the first
boot. This situation is however unsafe since the keys are publically
available.

For example, in the case of the NXP SE050, these keys would be
available in the OP-TEE source tree [2] and of course in the
documentation corresponding to the part.

To address that, users are required to rotate/provision those keys
(ie, generate new keys and write them in the secure element's
persistent memory).

For information on SCP03, check the Global Platform HomePage and
google for that term [1]
[1] globalplatform.org
[2] https://github.com/OP-TEE/optee_os/

Subject: arm: rmobile: Add HopeRun HiHope RZ/G2M board support

The HiHope RZ/G2M board from HopeRun consists of main board
(HopeRun HiHope RZ/G2M main board) and sub board(HopeRun
HiHope RZ/G2M sub board). The HiHope RZ/G2M sub board sits
below the HiHope RZ/G2M main board.

This patch adds the required board support to boot HopeRun HiHope
RZ/G2M board.

Subject: arm: rmobile: Add Silicon Linux EK874 board support

The EK874 development kit from Silicon Linux is made of CAT874 (the main
board) and CAT875 (the sub board that goes on top of CAT874).

This patch adds the required board support to boot Si-Linux EK874 board
based on R8A774C0 SoC.

DTS files apart from r8a774c0-ek874-u-boot.dts and r8a774c0-u-boot.dtsi
have been imported from Linux kernel 5.11 commit f40ddce88593
("Linux 5.11").

From 86e07d59ee53cdd209c114bdabef599d3b3d2036 Mon Sep 17 00:00:00 2001
From: Fabien Parent <fparent@baylibre.com>

Subject: board: mediatek: rename pumpkin board into mt8516

More than one pumpkin board has been made with different MediaTek SoCs.
Rename the pumpkin board to follow the naming convention of all
other MediaTek boards and also to not be confusing when other pumpkin
boards will be added in follow-up commits.

From b00f0066e52413e0f8fd4a84681e6e27c4270c26 Mon Sep 17 00:00:00 2001
From: Simon Glass <sjg@chromium.org>
Date: Wed, 3 Feb 2021 06:01:02 -0700
Subject: dtoc: Support tracking the phase of U-Boot

U-Boot operates in several phases, typically TPL, SPL and U-Boot proper.
The latter does not use dtoc.

In some rare cases different drivers are used for two phases. For example,
in TPL it may not be necessary to use the full PCI subsystem, so a simple
driver can be used instead.

This works in the build system simply by compiling in one driver or the
other (e.g. PCI driver + uclass for SPL; simple_bus for TPL). But dtoc has
no way of knowing which code is compiled in for which phase, since it does
not inspect Makefiles or dependency graphs.

So to make this work for dtoc, we need to be able to explicitly mark
drivers with their phase. This is done by adding an empty macro to the
driver. Add support for this in dtoc.

Subject: dtoc: Support headers needed for drivers

Typically dtoc can detect the header file needed for a driver by looking
for the structs that it uses. For example, if a driver as a .priv_auto
that uses 'struct serial_priv', then dtoc can search header files for the
definition of that struct and use the file.

In some cases, enums are used in drivers, typically with the .data field
of struct udevice_id. Since dtoc does not support searching for these,
add a way to tell dtoc which header to use. This works as a macro included
in the driver definition.

Subject: dtoc: Generate uclass devices

Add support for generating a file containing uclass instances. This avoids
the need to create these at run time.

Update a test uclass to include a 'priv_auto' member, to increase test
coverage.

Subject: linker_lists: Allow use in data structures

At present linker lists are designed for use in code. They make use of
statements within expressions ({...}), for example.

It is possible to generate a reference to a linker_list entry that can
be used in data structures, where such features are not permitted. It
requires that the reference first be declared as extern. In other
words the existing macro needs to be split into two parts.

Add new macros to support this.

Subject: dm: core: Add macros to access the new linker lists

Add macros which work with instantiated devices and uclasses, as created
at build time by dtoc. Include variants that can be used in data
structures.

These are mostly used by dtoc but it is worth documenting them fully for
the occasional case where they might come up in user code.

Subject: efi_loader: Add device path related functions for initrd via Boot####

On the following patches we allow for an initrd path to be stored in
Boot#### variables.  Specifically we encode in the FIlePathList[] of
the EFI_LOAD_OPTIONS for each Boot#### variable.

The FilePathList[] array looks like this:
kernel - 0xff - VenMedia(initrd GUID) - initrd1 - 0x01 initrd2 - 0xff
So let's add the relevant functions to concatenate and retrieve a device
path based on a Vendor GUID.

Subject: efi_loader: Add helper functions for EFI

A following patch introduces a different logic for loading initrd's
based on the EFI_LOAD_FILE2_PROTOCOL.
Since similar logic can be applied in the future for other system files
(i.e DTBs), let's add some helper functions which will retrieve and
parse file paths stored in EFI variables.

Subject: efi_loader: Replace config option for initrd loading

Up to now we install EFI_LOAD_FILE2_PROTOCOL to load an initrd
unconditionally. Although we correctly return various EFI exit codes
depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the
kernel loader, only falls back to the cmdline interpreted initrd if the
protocol is not installed.

This creates a problem for EFI installers, since they won't be able to
load their own initrd and continue the installation. It also makes the
feature hard to use, since we can either have a single initrd or we have
to recompile u-boot if the filename changes.

So let's introduce a different logic that will decouple the initrd
path from the config option we currently have.
When defining a UEFI BootXXXX we can use the filepathlist and store
a file path pointing to our initrd. Specifically the EFI spec describes:

"The first element of the array is a device path that describes the device
and location of the Image for this load option. Other device paths may
optionally exist in the FilePathList, but their usage is OSV specific"

When the EFI application is launched through the bootmgr, we'll try to
interpret the extra device path. If that points to a file that exists on
our disk, we'll now install the load_file2 and the efi-stub will be able
to use it.

This opens up another path using U-Boot and defines a new boot flow.
A user will be able to control the kernel/initrd pairs without explicit
cmdline args or GRUB.

Subject: efi: Add ESRT to the EFI system table

The ESRT is initialised during efi_init_objlist after
efi_initialize_system_table().

The ESRT is recreated from scratch at the following events:
- successful UpdateCapsule;
- FMP instance install.

The code ensures that every ESRT entry has a unique fw_class value.

Limitations:
- The ESRT is not updated if an FMP instance is uninstalled;
- the fields image_type and flags are in the current implementation left
undefined. Setting these values will require a per-platform function
that returns the image_type/flags as a function of the image fw_class.

Remove two EFI_CALL() indirections.
Move ESRT GUID in efidebug's list of GUIDs.

Subject: dm: Rename device_get_by_driver_info_idx()

This function finds a device by its driver_info index. With
of-platdata-inst we do not use driver_info, but instead instantiate
udevice records at build-time.

However the semantics of using the function are the same in each case:
the caller provides an index and gets back a device.

So rename the function to device_get_by_ofplat_idx(), so that it can be
used for both situations. The caller does not really need to worry about
the details.

Subject: sandbox: i2c: Support i2c emulation with of-platdata

At present the i2c emulators require access to the devicetree, which is
not possible (by design) with of-platdata.

Add a way for drivers to record the of-platdata index of their emulator,
so that we can still find the emulator.

This allows i2c emulation to work with of-platdata.

Subject: dm: core: Create a struct for device runtime info

At present when driver model needs to change a device it simply updates
the struct udevice structure. But with of-platdata-inst most of the fields
are not modified at runtime. In fact, typically only the flags need to
change.

For systems running SPL from read-only memory it is convenient to separate
out the runtime information, so that the devices don't need to be copied
before being used.

Create a new udevice_rt table, similar to the existing driver_rt. For now
it just holds the flags, although they are not used in this patch.

Add a new Kconfig for the driver_rt data, since this is not needed when
of-platdata-inst is used.

Subject: dm: core: Move flags to device-runtime info

When of-platdata-inst is active, use the flags in the new udevice_rt
table, dropping them from the main struct udevice. This ensures that the
latter is not updated at runtime.

Subject: dm: core: Allow storing priv/plat data separately

At present the device priv/data data allocated by dtoc is stored in the
data section along with other variables. On some platforms it is better
to allocate space for it separately, e.g. if SPL is running from read-only
memory.

Create a new space with the same size as that allocated by dtoc, ready for
use.

Subject: dm: core: Use separate priv/plat data region

Make use of the new priv/plat data region if enabled. This is implemented
as a simple offset from the position set up by dtoc to the new position.

So long as all access goes through dm_priv_to_rw() this is safe.

dfu_free_entities() invoking dfu_free_entity_sf() has let to segementation
faults due to double freeing the same device.

spi_flash_free() is not relevant for the driver model but exists only for
compatibility with old drivers.

We must not remove any device here:

Subject: x86: coral: Put the eMMC first

At present the eMMC device does not have an alias so it appears after
the SD card which is device 1. There is no device 0 which is odd.

Make the eMMC device be the first one. Update the boot script to use the
new device.

originally conceived. Add the structures for these.

Also rename attributes_offset to something shorter, to ease code

Subject: smbios: Allow writing to the coreboot version string

When U-Boot is booted from coreboot the SMBIOS tables are written by
coreboot, not U-Boot. The existing method of updating the BIOS version
string does not work in that case, since gd->smbios_version is only set
when U-Boot writes the tables.

Add a new function which allows the version to be updated by parsing the
tables and writing the string in the correct place. Since coreboot
provides a pointer to the SMBIOS tables in its sysinfo structure, this
makes it easy to do the update.

In some cases CBFS does not start with a header but is just a collection

is provided.

Update the cbfs_init_mem() function to support this.

Subject: sandbox: Provide a way to bind fixed/removeable devices

At present when a file is bound to a host device it is always marked as
removeable. Arguably the device is removeable, since it can be unbound at
will. However while it is bound, it is not considered removable by the
user. Also it is useful to be able to model both fixed and removeable
devices for code that distinguishes them.

Add a -r flag to the 'host bind' command and plumb it through to provide
this feature.

Subject: sandbox: image: Allow sandbox to load any image

Sandbox is special in that it is used for testing and it does not match
any particular target architecture. Allow it to load an image from any
architecture, so that 'bootm' can be used as needed.

Subject: sf: Support querying write-protect

This feature was dropped from U-Boot some time ago:

   f12f96cfaf5 (sf: Drop spl_flash_get_sw_write_prot")

However, we do need a way to see if a flash device is write-protected,
since if it is, it may not be possible to write to do (i.e. failing to
write is expected).

I am not sure of the correct layer to implement this, so this patch is a
stab at it. If spi-flash makes sense then I will add to the 'sf' also.

Re the points mentioned in the removal commit:

    1) This kind of requirement can be achieved using existing
       flash operations and flash locking API calls instead of
       making a separate flash API.

Which uclass is this?

    2) Technically there is no real hardware user for this API to
       use in the source tree.

I do want coral (at least) to support this.

    3) Having a flash operations API for simple register read bits
       also make difficult to extend the flash operations.

This new patch only mentions write-protect being on or off, rather than
the actual mechanism.

    4) Instead of touching generic code, it is possible to have
       this functionality inside spinor operations in the form of
       flash hooks or fixups for associated flash chips.

That sounds to me like what drivers are for. But we still need some sort
of API for it to be accessible.

Subject: xilinx: Sync DTs with Linux kernel

There are several changes which happen in mainline kernel which should get
also to U-Boot. Here is the list of patches from the kernel:

- ARM: zynq: Fix leds subnode name for zc702/zybo-z7
- arm64: dts: zynqmp: Fix leds subnode name for zcu100/ultra96 v1
- arm64: dts: zynqmp: Fix u48 si5382 chip on zcu111
- arm64: dts: zynqmp: Wire up the DisplayPort subsystem
- arm64: dts: zynqmp: Add DisplayPort subsystem
- arm64: dts: zynqmp: Add DPDMA node
- arm64: dts: zynqmp: Enable phy driver for Sata on zcu102/zcu104/zcu106
- arm64: dts: zynqmp: Enable si5341 driver for zcu102/106/111
- arm64: dts: zynqmp: Add DT description for si5328 for zcu102/zcu106
- arm64: dts: zynqmp-zcu100-revC: correct interrupt flags
- arm64: dts: xilinx: align GPIO hog names with dtschema
- arm64: zynqmp: Add Xilinx AES node
- dt: bindings: dma: xilinx: dpdma: DT bindings for Xilinx DPDMA

but also some other changes have been done.
- Using only one compatible string for adxl345 on zturn
- Remove Xilinx internal DP bindings
- Remove USB3.0 serdes configurations
- Remove SATA serdes configuration for zc1232
- Resort nvmem_firmware
- Update nand compatible string
- Aling power-domains property for sd0/1
