Simon Glass <[email protected]> says:
Each arch does something slightly different before booting the OS. Some
archs even do different things depending on the CPU type.
It is quite hard to know what actually happens in the final milliseconds
before the OS boot.
This series attempts to start cleaning up U-Boot in this area.
The basic intent is to create a new bootm_final() function which can be
called by all archs. It provides some flags for a couple of necessary
variations but otherwise it is generic.
All architectures are converted over to use this new function.
board_quiesce_devices() is moved into bootm_final() so that all archs
benefit from it.
This series fixes a bug in device_remove() is fixed where removing a
parent with specialised flags (e.g. DM_REMOVE_ACTIVE_ALL) could leave
children activated, since they do not match the flags. This fixes is
needed to avoid bootm_final() causing test failures on sandbox.
Future work could take this a little further:
- Convert EFI loader to use the same function
- Improve comments for cleanup_before_linux() across architectures
- Support fake-run tracing on all archs

ARM stashes bootstage data to a known memory location before booting,
so the kernel can pick it up. Add this to bootm_final() so all
architectures benefit from it.
The bootstage_stash_default() function is a no-op when bootstage or
stashing is disabled.

The RISC-V announce_and_cleanup() duplicates the common pre-boot
steps. Replace it with a call to bootm_final().
Move board_quiesce_devices() into bootm_final() so it is available to
all architectures. Drop the RISC-V weak definition and header
declaration since the generic one in bootm.h is used instead.

There are various functions which announce that booting is imminent and
do related preparation. Most of these are arch-specific.
In practice, most archs do a similar thing. It would be better to
have a common function, with perhaps some events for things that are
really arch- and board-specific.
Create a new bootm_final() function with the common pre-boot steps:
printing the "Starting kernel" message, recording bootstage data,
optionally writing bootstage to the FDT and printing a report, and
removing active devices.
Be careful to avoid using BIT() macros which are not available with host
tools.

FIT images don't work without having to explicitly specify physical
load addresses. Digging into that it looks like a flaw in
bootm_load_os().
It duplicates images->os for convenience. However, the code handling
"kernel_noload" images then updates the load address in the copy with
the value lmb_alloc_mem() returned. Later there's another call to
lmb_alloc_mem() that uses the old value. This leads to havoc due
to subsequent calls of lmb_alloc_mem() picking too low addresses.
The "fix" is to mark the local variable const to avoid accidental
assignments. This works but IMO the logic is still flawed somehow as
this leads to overlapping lmb reservations. I guess the fixed
reservation should only be done when the noload path wasn't hit.

There currently are multiple allocation API's in the LMB module. There
are a couple of API's for allocating memory(lmb_alloc() and
lmb_alloc_base()), and then there are two for requesting a reservation
for a particular memory region (lmb_reserve() and
lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will
cater to all types of allocation requests and replace lmb_reserve()
and lmb_alloc_addr() with the new API.
Moreover, the lmb_reserve() API is pretty similar to the
lmb_alloc_addr() API, with the one difference being that the
lmb_reserve() API allows for reserving any address passed to it --
the address need not be part of the LMB memory map. The
lmb_alloc_addr() does check that the address being requested is
actually part of the LMB memory map.
There is no need to support reserving memory regions which are outside
the LMB memory map. Remove the lmb_reserve() API functionality and use
the functionality provided by lmb_alloc_addr() instead. The
lmb_alloc_addr() will check if the requested address is part of the
LMB memory map and return an error if not.

When building with only bootz command, without bootm, images pointer
inside bootm_info structure is not initialized. And since this structure
is stored in stack, the generated error is kind of random, but most of
the time this will generate: "ramdisk - allocation error".
Also, after analysis, this problem could occur with the command booti,
if the command bootm is disabled.
Currently bootm_init() is called by: do_bootz(), do_bootm(), do_booti()
and by do_stm32prog(). And all of these commands execute bootm_run_states()
which access the images pointer stored into bootm_info structure.
So, to fix this issue, just do the assignment unconditionally.

Currently, when decompressing a gzip-compressed image during bootm, a
generic error such as "inflate() returned -5" is shown when the buffer is
too small. However, it is not immediately clear that this is caused by
CONFIG_SYS_BOOTM_LEN being too small.
This patch improves error handling by:
- Detecting Z_BUF_ERROR (-5) returned from the inflate() call
- Suggesting the user to increase CONFIG_SYS_BOOTM_LEN when applicable
- Preserving the original return code from zunzip() instead of overwriting
it with -1
By providing clearer hints when decompression fails due to insufficient
buffer size, this change helps users diagnose and fix boot failures more
easily.

USB is stopped using driver model now, in dm_remove_devices_flags() in
announce_and_cleanup() at the top of this file.
The usb_stop() call actually unbinds devices.
When a USB device is unbound, it causes any bootflows attached to it to
be removed, via a call to bootdev_clear_bootflows() from
bootdev_pre_unbind(). This obviously makes it impossible to boot the
bootflow.
However, when booting a bootflow that relies on USB, usb_stop() is
called, which unbinds the device. At that point any information
attached to the bootflow is dropped.
This is quite risky since the contents of freed memory are not
guaranteed to remain unchanged. Depending on what other options are
done before boot, a hard-to-find bug may crop up.
Drop the call to this old function.
Leave the netconsole call there, since this needs conversion to
driver model.

commit 97707f12fdab ("tpm: Support boot measurements") moved out code
from the EFI subsystem into the TPM one to support measurements when
booting with !EFI.
Those were moved directly into the TPM subsystem and in the tpm-v2.c
library. In hindsight, it would have been better to move it in new
files since the TCG2 is governed by its own spec, it's overeall cleaner
and also easier to enable certain parts of the TPM functionality.
So let's start moving the headers in a new file containing the TCG
specific bits.

There is a description for ACPI in 3.3.4.1 PCR[0] – SRTM, POST BIOS,

no mention of ACPI in 3.3.4.2 PCR[1] – Host Platform Configuration.
However, in Figure 6 -- PCR Mapping of UEFI Components ACPI is shown
in PCR1. The general description also mentions PCR0 is for code and PCR1
is for data such as ACPI and SMBIOS.
So let's switch over the DTB measurements to PCR1 which seems a better

Change type of ulong env_get_bootm_low() to phys_addr_t env_get_bootm_low().
The PPC/LS systems already treat env_get_bootm_low() result as phys_addr_t,
while the function itself still returns ulong. This is potentially dangerous
on 64bit systems, where ulong might not be large enough to hold the content
of "bootm_low" environment variable. Fix it by using phys_addr_t, similar to
what env_get_bootm_size() does, which returns phys_size_t .

Sometimes the kernel is built as an EFI application rather than a
binary. We still want to support compression for this case.
For arm64 the entry point is set later in the bootm_load_os() function,
since these images are typically relocated due to the 2MB-alignment
requirement of arm64 images. But since the EFI image is not in the same
format, we need to update the entry point earlier.
Set the entry point always, for kernel_noload to resolve this problem.
It should be harmless to do this always.

The problem is that the arm64 magic is checked before the image is
decompressed. However this is only part of it. The kernel_noload image
type doesn't work with compression, since the kernel is not loaded. So
this series deals with that by using an lmb-allocated buffer for the
uncompressed kernel.
Another issue is that the arm64 handling is done too early, before the
image is loaded. This series moves it to after loading, so that
compression can be handled.
A patch is included to show the kernel load-address, so it is easy to
see what is going on.
One annoying feature of arm64 is that the image is often copied to
another address. It might be possible for U-Boot to figure that out
earlier and decompress it to the right place, but perhaps not.
With all of this it should be possible to boot a compressed kernel on
any of the 990 arm64 boards supported by Linux, although I have only
tested two.

only called if the condition is met - see bootm_os_get_boot_func()

The normal bootm flow calls bootm_find_other() can call the
BOOTM_STATE_FINDOTHER state as part of its processing. Fix the
condition there so that this hack can be removed.

The Android mechanism uses the loadaddr envrionment-variable to get the
load address, if none is provided. This is equivalent to
image_load_addr so use that instead, converting it to a string as
needed.
This change will permit passing img_addr to this function, in a future
change.

This function only uses two arguments. The 'arch' always has a constant
value, so drop it. This simplifies the function call.
