Based on the existing work done by Simon Glass this series adds
support for booting aarch64 devices using ACPI only.
As first target QEMU SBSA support is added, which relies on ACPI
only to boot an OS. As secondary target the Raspberry Pi4 was used,
which is broadly available and allows easy testing of the proposed
solution.
The series is split into ACPI cleanups and code movements, adding
Arm specific ACPI tables and finally SoC and mainboard related
changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the
mandatory ACPI tables are supported, allowing to boot into Linux
without errors.
The QEMU SBSA support is feature complete and provides the same
functionality as the EDK2 implementation.
The changes were tested on real hardware as well on QEMU v9.0:
qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \
-pflash secure-world.rom \
-pflash unsecure-world.rom
qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \
-smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \
-dtb bcm2711-rpi-4-b.dtb -nographic
Tested against FWTS V24.03.00.
Known issues:
- The QEMU rpi4 support is currently limited as it doesn't emulate PCI,
USB or ethernet devices!
- The SMP bringup doesn't work on RPi4, but works in QEMU (Possibly
cache related).
- PCI on RPI4 isn't working on real hardware since the pcie_brcmstb
Linux kernel module doesn't support ACPI yet.

Support reading the "interrupts" property from the devicetree in case
the "interrupts-extended" property isn't found. As the "interrupts"
property is commonly used, this allows to parse all existing FDT and
makes irq_get_by_index() more useful.
The "interrupts" property doesn't contain a phandle as "interrupts-extended"
does, so implement a new method to locate the interrupt-parent called
irq_get_interrupt_parent().
TEST: Read the interrupts from the GIC node for ACPI MADT generation.

When OSCCA is enabled, FSB fuse shadow (offset 0x8000)
access is disabled for SOC. So update the driver to read fuse
from ELE API. The ELE has supported to read all shadow fuses like
FSB, reuse the table of FSB for the word index used by ELE API.
Add ELE shadow fuse read and write to current ELE fuse driver.
But when LC is OEM closed, the ELE read/write shadow fuse APIs are
forbidden. Reading from any fuse will return error. This causes
problem to u-boot which must read out some fuse no matter whatever LC.
So we have to change back to read from FSB and ELE common fuse read API.
For using ELE shadow read API for development purpose like checking
the ELE shadow fuse write result, user can set env variable
"enable_ele_shd" to y to switch it.

There is a bug when checking fuse word with redundancy fuse in FSB
table. The redundancy fuses are combined into 4 words, so we can't
directly use word index to do the check, otherwise the high 4 words
will fail to match.
And When calling ELE API, res parameter will pass to ELE API to get ELE
response value for failure. So most of usage does not initialize
this variable and print it after calling ELE API.
However, when ELE API returns failure, we can't ensure this res is
always set because there may be other failure like MU failure.

Simon Glass <[email protected]> says:
When the SPL build-phase was first created it was designed to solve a
particular problem (the need to init SDRAM so that U-Boot proper could
be loaded). It has since expanded to become an important part of U-Boot,
with three phases now present: TPL, VPL and SPL
Due to this history, the term 'SPL' is used to mean both a particular
phase (the one before U-Boot proper) and all the non-proper phases.
This has become confusing.
For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL'
phases, not just SPL. So code which can only be compiled for actual SPL,
for example, must use something like this:
#if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)
In Makefiles we have similar issues. SPL_ has been used as a variable
which expands to either SPL_ or nothing, to chose between options like
CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable
was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was
updated to support 'VPL_' as well.
This series starts a change in terminology and usage to resolve the
above issues:
- The word 'xPL' is used instead of 'SPL' to mean a non-proper build
- A new CONFIG_XPL_BUILD define indicates that the current build is an
'xPL' build
- The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now
defined for TPL and VPL phases
- The existing SPL_ Makefile variable is renamed to SPL_
- The existing SPL_TPL Makefile variable is renamed to PHASE_
It should be noted that xpl_phase() can generally be used instead of
the above CONFIGs without a code-space or run-time penalty.
This series does not attempt to convert all of U-Boot to use this new
terminology but it makes a start. In particular, renaming spl.h and
common/spl seems like a bridge too far at this point.
The series is fully bisectable. It has also been checked to ensure there
are no code-size changes on any commit.

The ATSHA204A chip requires SDA line to go low for at least 60us to
wake up the chip. Previous implementation did not meet this requirement
due to the NAK received on bus and not sending the zeroes.
The function to ignore the NAK and send bytes regardless is not
supported in the u-boot making it impossible to wake up the chip
this way.
Instead, the bus speed, if needed, is set to lowest value and the
message is sent to the address 0x0. This way, the address of zero
makes the SDA line go low for about 80us, meeting the required time
to wake up the chip. The zero length packet is not sent by the i2c,
so the one byte is sent to the transfer function, but only the address
is sent anyway.
After sending the zero address, the bus speed is restored to the
previous value if it was slowed down to wake up the chip.

this is not done consistently during boot.

To quote the author:
It would be useful to be able to boot an OS when CONFIG_CMDLINE is
disabled. This could allow reduced code size.
Standard boot provides a way to handle programmatic boot, without
scripts, so such a feature is possible. The main impediment is the
inability to use the booting features of U-Boot without a command line.
So the solution is to avoid passing command arguments and the like to
code in boot/
A similar process has taken place with filesystems, for example, where
we have (somewhat) separate Kconfig options for the filesystem commands
and the filesystems themselves.
This series starts the process of refactoring the bootm logic so that
it can be called from standard boot without using the command line.
Mostly it removes the use of argc, argv and cmdtbl from the internal
logic.
Some limited tidy-up is included, but this is kept to smaller patches,
rather than trying to remove all #ifdefs etc. Some function comments
are added, however.
A simple programmatic boot is provided as a starting point.
This work will likely take many series, so this is just the start.
Size growth with this series for firefly-rk3288 (Thumb2) is:
arm: (for 1/1 boards) all +23.0 rodata -49.0 text +72.0
This should be removed by:
https://source.denx.de/u-boot/custodians/u-boot-dm/-/issues/11
but it is not included in this series as it is already large enough.
No functional change is intended in this series.
Changes in v3:
- Add a panic if programmatic boot fails
- Drop RFC tag
Changes in v2:
- Add new patch to adjust position of unmap_sysmem() in boot_get_kernel()
- Add new patch to obtain command arguments
- Fix 'boot_find_os' typo
- Pass in the command name
- Use the command table to provide the command name, instead of "bootm"
