Recently, gru boards were migrated to use common stack addresses with
U-Boot commit 5e7cd8a11995 ("rockchip: Use common bss and stack
addresses on RK3399") and commit 49f8131e5594 ("rockchip: rk3399-gru:
Use TPL with common bss and stack addresses"). This is done with the
ROCKCHIP_COMMON_STACK_ADDR config.
With POSITION_INDEPENDENT, INIT_SP_RELATIVE defaults to enabled as well.
However, ROCKCHIP_COMMON_STACK_ADDR selects HAS_CUSTOM_SYS_INIT_SP_ADDR,
which depends on INIT_SP_RELATIVE being disabled. So this results in a
configuration warning:
WARNING: unmet direct dependencies detected for HAS_CUSTOM_SYS_INIT_SP_ADDR
Depends on [n]: ARM [=y] && ARCH_KIRKWOOD [=n] || ARC [=n] || ARM [=y] && !INIT_SP_RELATIVE [=y] || MIPS [=n] || PPC [=n] || RISCV [=n]
Selected by [y]:
- ROCKCHIP_COMMON_STACK_ADDR [=y] && ARM [=y] && ARCH_ROCKCHIP [=y] && SPL_SHARES_INIT_SP_ADDR [=y]
I'm not sure if adhering to the Rockchip values means we can't be
position-independent. Disabling INIT_SP_RELATIVE still appears to keep
my kevin board working, so let's do that for now.

Apply our preserved changes to the new U-Boot defconfigs. Upstream
rearranged memory layouts for Rockchip boards to a unified layout, which
got rid of CUSTOM_SYS_INIT_SP_ADDR and HAS_CUSTOM_SYS_INIT_SP_ADDR, and
will need a change to a related INIT_SP_RELATIVE later.
Normalize the positions of each line in the config by regenerating the
defconfig by `./mk -l u-boot` and then `./mk -s u-boot`, so that the
diff looks all green when we actually expand it to the full config.

Set the U-Boot revision to the commit hash for v2025.04, and rebase the
patches for the default U-Boot tree to accommodate for upstream changes:
- The SPL/TPL/VPL phases are being unified under the xPL name, so
there's a config rename.
- Some test macros were renamed, for the video-related patches.
- Add some missing hunks for video damage series.
- Upstream Makefile adds another argument to the binman call.
- The SWIG related patch is merged upstream, drop it.
I'm not sure if src/u-boot/* directories are regenerated on new builds,
so it may be necessary to remove them manually after applying this.

Run diffconfig from Linux to track our modifications to the old upstream
defconfigs, so we can apply them to the new ones. Restore the original
defconfigs to highlight our changes here, and upstream changes in the
next commit. Done manually, but something like:

Swig 4.3.0. Context here:

scripts/dtc/pylibfdt/libfdt.i_shipped: Use SWIG_AppendOutput
This patch from U-Boot upstream has been backported to the
release revision used by Libreboot. Swig has, since 4.3.0,
changed the language-specific AppendOutput functions, but
the helper macro SWIG_AppendOutput is identical; therefore,
upstream switched to this function.
The benefit of this fix is that since the newly used macro
is also the same on older Swig versions, and behaves the same,
this shouldn't fix building on older Swig versions. For reference,
the initial Libreboot 20241206 release, and revisions of it before
revision 8, was built on Debian 12 which uses Swig 4.1.0.
The rev8 release will still be compiled on Debian 12, but with
this change, it should also compile on Debian Sid, and bleeding
edge distros like Arch Linux.

The bootflow menu is already the default boot command on x86. Switch
arm64 boards to that as well, so instead of booting the first thing we
find, we can easily choose what to boot.
Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
Otherwise, you have to press enter to boot your distro.
With this, a timeout is created. After a number of seconds,
which can be reconfigured, the first option selected will be booted,
when generating a bootflow menu.
The timeout is disabled when you navigate the menu; it only
kicks in if you don't input anything on the keyboard.
More information about how this works is in the U-Boot patches,
within this patch. I've set the timeout to 8 seconds.

Otherwise, you have to press enter to boot, which is unacceptable
for headless operation.
Pressing anything other than enter an an option, such as the arrow
keys, will disable the timeout.

We need to initialize the USB subsystem before we can use USB devices
like keyboards and external disks, by running `usb start`. Use the
PREBOOT config option to run the necessary command before U-Boot tries
to automatically boot anything. It's already enabled for boards other
than gru_kevin and gru_bob, so just update those two configs.

Set default U-Boot revision to v2024.10 and rebase patches on top of
that. The video subsystem now has switched to using the 'cyclic'
mechanism, so the code around one of the video patches changed a bit.
x86 boards were already switched to v2024.10. Update U-Boot for the
remaining ARM64 boards as usual:
- Turn old configs into defconfigs (./update trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update trees -f u-boot)
- Review the diffconfigs to see if any options were renamed upstream
- Copy over the new upstream defconfigs and apply earlier diff
- Turn new defconfigs into configs (./update trees -l u-boot)

This is a patch from Simon Glass. U-Boot clears the display
when it starts up, but was asking the VESA driver to do the
same, needlessly; this patch avoids the latter.
A further patch is also included, which provides a better
message when jumping into long mode on the SPL (64-bit) target,
dumping it on the serial console instead of using printf.

U-Boot was hanging on hardware, but not Qemu. This is because on
the machines tested, namely the X200 and E6230 laptops supported
in Libreboot, the UART was disabled from coreboot.
This U-Boot patch from Simon Glass works around the issue by
silently disabling the UART when it isn't there. Instead,
output is sent to the display and U-Boot no longer hangs.

It's a new experimental payload in Libreboot, so we may aswell
start with the very latest release of U-Boot.

Currently seems to stall when booted from the GRUB
payload, but works when booted from the SeaBIOS menu.
I also tested it as a standalone payload and it seems
to boot. Will test on hardware next, and start adding
it to more mainboards.

NOTE: Support added for xarch target x86_64-elf,
but U-Boot failed to build with this error:
OBJCOPY lib/efi_loader/helloworld.efi
x86_64-elf-objcopy: lib/efi_loader/helloworld_efi.so: invalid bfd target
make[2]: *** [scripts/Makefile.lib:476: lib/efi_loader/helloworld.efi] Error 1
Since I'm building U-Boot for x86_64 *on* an x86-64
host, and since that is currently the recommended type
of machine to use for lbmk development, and since the
other x86 payloads currently don't cross compile anyway,
this is an acceptable compromise for now. This is because
at present, I'm not making U-Boot the primary payload on x86,
instead preferring to chain it from GRUB and SeaBIOS.
The target.cfg file for x86 u-boot shows xarch/xtree commented.
Uncomment these to compile on crossgcc instead of hostcc.
I mention 64-bit because I initially did this first, but decided
to do 32-bit first. I'll work on the 64-bit one next (SPL).
It's only enabled in QEMU for now.

U-Boot has migrated to using upstream device-tree files for gru boards,
but the clock driver doesn't yet support setting rates for a certain
clock that upstream uses for the eDP display. It happens to work without
it, so for now remove the clock setting until the driver is fixed.

Commit 46e01c0e1d ("u-boot: Avoid building U-Boot-only binman images")
added a patch that prevents an error while building U-Boot, due to some
U-Boot images needing a copy of BL31 that we are not passing in.
Removing build instructions for these images isn't really necessary,
when we can instead tell the build tool that it shouldn't exit with an
error. It checks a BINMAN_ALLOW_MISSING environment variable for this,
but just unconditionally replace the check with the argument.

Set default U-Boot revision to v2024.07 and rebase patches on top of
that. One patch that fixes drawing box characters (UTF-8 to CP437) had
an alternative merged, another hack we have to fix regulator issues is
no longer neccessary as the issue is fixed, and my QEMU patches were
merged upstream, so drop these patches. One patch we have to disable
binman images can be replaced by a simpler alternative so drop it too.
Upstream kconfig status is still unstable, so updating configs with
`make oldconfig` would miss important upstream changes, since they rely
on carrying defaults via upstream defconfigs. Update the configs as
such, like before:
- Turn old configs into defconfigs (./update trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update trees -f u-boot)
- Review the diffconfigs to see if any options were renamed upstream
- Copy over the new upstream defconfigs and apply earlier diff
- Turn new defconfigs into configs (./update trees -l u-boot)

certain code checks for build.list, to skip it, for
example in items()
we already use config/data/grub to store grub config data
that applied to all trees
create these directories too:
config/data/coreboot
config/data/u-boot
config/data/seabios
move the respective build.list files in here, and also
to config/data/grub
now multi-tree projects contain, per directory, just the
target.cfg file and the patches directory. this is much
cleaner, because some of the logic can be simplified more

build all of the defined crossgccc targets
crossgcc_ada is now xlang, and defines which languages
to build, rather than whether to build gcc-gnat

only call crossgcc for coreboot and u-boot, but use
hostcc for everything else. simplify the checking of
which architecture to compile for. "arch" in target.cfg
files has been modified, to allow further simplification.
without this patch, the logic currently only *barely* avoids
using crossgcc on things like utils, and only works in practise
because, in practise, lbmk only works on x86_64 anyway.
the new logic, as per this patch, is simpler and more robust.
