Alper Nebi Yasak 708fc14c60 u-boot: Fix display initialization on gru boards
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.

Alper Nebi Yasak 0cc7736b40 u-boot: Avoid breaking build for U-Boot-only binman images
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.

Alper Nebi Yasak 2ecec55af7 u-boot: Update to v2024.07
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)

Leah Rowe c6d243af93 u-boot: don't define xarch in default
it's only needed for each board

Leah Rowe eff9130b7a update/trees: further simplify crossgcc handling
arch no longer needs to be set, on multi-tree projects,
and it has been renamed to xarch

the new behaviour is: if xarch is set, treat it as a
list of crossgcc targets and go through the list. set
the first one as the target, for what lbmk builds, but
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

Leah Rowe 90ac30b163 update/trees: simplified crossgcc handling
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.

Alper Nebi Yasak 444f2899e6 u-boot: qemu_arm64_12mb: Enable video console
Add my upstream U-Boot series enabling video console support by default
for QEMU ARM virtual machines. Similarly, enable the related config
options for our builds using savedefconfig and olddefconfig.

The resulting ROM can be booted with a command line like:

    qemu-system-aarch64 \
        -machine virt,secure=on,virtualization=on \
        -cpu cortex-a72 -m 1G \
        -serial stdio -device VGA \
        -device qemu-xhci \
        -device usb-kbd -device usb-mouse \
        -bios bin/qemu_arm64_12mb/*.rom

Alper Nebi Yasak 46e01c0e1d u-boot: Avoid building U-Boot-only binman images
For Rockchip boards U-Boot tries to build SPI and MMC images that
require an externally built BL31 file to be provided, and the build
fails otherwise. This is not really as configurable as it should be.

In Libreboot, we only care about the build outputs for U-Boot proper.
There is a BL31 built during our coreboot builds, but using that in
U-Boot builds is a chicken-and-egg problem. Building BL31 outside the
coreboot build and passing it to both projects is possible, but needs
work.

For now, stop trying to build these U-Boot-only images as a workaround,
by removing the binman image descriptions from the device-tree sources.
Additionally, disable in our configs the BINMAN_FDT functionality that
allows using these at runtime as it requires them to be present.

Alper Nebi Yasak 5b4ced3329 u-boot: Add patch to avoid regulator errors
U-Boot upstream has added a reference counting for regulator enable
actions which somehow makes gru-kevin unbootable. Add a workaround
that makes it work again.

Alper Nebi Yasak f459e05ecd u-boot: Update to v2023.10
Set default U-Boot revision to v2023.01 and rebase patches on top of
that. Another series about 16x32 fonts was merged upstream, so drop some
now-unnecessary patches we had for that. For the video damage tracking
series, switch to the version I'm trying to upstream.

Upstream kconfig status is a bit 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:

- Turn old configs into defconfigs (./update project trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)

- 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 project trees -l u-boot)
