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)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update project 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 project trees -l u-boot)
