U-Boot can be configured via environment variables which can be saved to
various storage devices. This usually defaults to MMC or SPI depending
on where it boots from, but assumes the device's layout is controlled by
U-Boot.
We should store the environment in SPI flash, but we also need to
configure coreboot FMAPs to reserve the area U-Boot would use as its
environment storage. For now, disable environment storage by setting
ENV_IS_NOWHERE=y to avoid overwriting random regions of SPI or MMC if
someone tries to save the variables.

Set default U-Boot revision to v2023.01 and rebase patches on top of
that. Upstream kconfig status is a bit unstable, so updating configs
with `make oldconfig` would miss important upstream changes.
For each board, run `make savedefconfig` and `diffconfig -m` at the old
version to get a diff from upstream defconfigs. Fix those affected by
upstream changes, like SYS_TEXT_BASE being renamed to TEXT_BASE. Then
append those to the new version's defconfigs and run `make olddefconfig`
to get updated configs.

The USB 2.0 ports on Exynos boards need the relevant driver enabled by
USB_EHCI_EXYNOS. This is enabled by default depending on USB_EHCI_HCD.
It's already enabled on snow and spring, but apparently not on peach
boards, as discovered from other people's attempts to enable it [1][2].
Enable it also on the peach_pi and peach_pit.

The display driver on the veyron boards needs reset drivers, more
specifically RESET_ROCKCHIP. This is enabled by default depending on
DM_RESET, which an upstream commit enables for veyron_jerry claiming it
fixes the display [1]. Enable it also in our configs, but for other
veyrons as well.

The configs were enabling SeaBIOS payload, but this is to be
handled by lbmk, not coreboot.
Further, they were enabling VGA ROM execution in coreboot, but
this should be handled by SeaBIOS.
This board should not have a GRUB payload enabled either; this
will be checked and fixed if necessary in the next commit.

Add a build for QEMU AArch64 virtual machine using U-Boot as payload.
Coreboot config is based on the following defconfig:
CONFIG_CBFS_SIZE=0x00c00000
CONFIG_BOARD_EMULATION_QEMU_AARCH64=y
CONFIG_CONSOLE_CBMEM_BUFFER_SIZE=0x20000
CONFIG_COREBOOT_ROMSIZE_KB_12288=y
CONFIG_UART_PCI_ADDR=0x0
The resulting ROM can be booted with a command line like:
qemu-system-aarch64 \
-machine virt,secure=on,virtualization=on \
-cpu cortex-a53 -m 1G \
-vga none -display none -serial stdio \
-bios bin/qemu_arm64_12mb/uboot_*.rom
However, this is little more than a proof of concept because U-Boot
upstream is missing coreboot integration on non-x86 boards, which could
have been useful for e.g. a framebuffer.

Add a U-Boot payload build for the QEMU AArch64 virtual machine. The
config is same as upstream "qemu-arm64" defconfig, but SYS_TEXT_BASE is
set to 0x50000000 so that it doesn't conflict with coreboot. QEMU
auto-generates and passes a device-tree file to U-Boot at runtime,
there's no compile-time canonical version, so there's no need to set
REMAKE_ELF or OF_EMBED.
It's not immediately obvious if QEMU-specific drivers are available to
support display output, but most coreboot integration is unavailable
(depends on x86) and entire video subsystem is disabled in the U-Boot
upstream defconfig.

U-Boot runtime configuration is done with a device-tree file, which is
built alongside the executable in the upstream build system, and must be
available to U-Boot at runtime.
This device-tree is normally not linked into the default "u-boot" ELF
file. So far we have been handling it by re-creating a "u-boot.elf" from
the raw binary parts by setting REMAKE_ELF, and using that as the
coreboot payload. Unfortunately, that fails to build for x86 boards,
more specificly the "coreboot" boards upstream.
It's also possible (but discouraged) to set OF_EMBED to embed the
device-tree file into the U-Boot itself, in which case we could use the
"u-boot" file as the payload on the "coreboot" boards. Add support for
using the "u-boot" file as the payload if "u-boot.elf" doesn't exist.

Add a series posted to upstream mailing lists that makes the GRUB
text-mode console faster by implementing video damage tracking [1].
Refresh the config files to include its new VIDEO_DAMAGE Kconfig.
Patch 7/7 upstream has a tiny conflict with "Improve UEFI experience"
series we already have, but it's only in the diff context. No changes
other than fixing that.

this is a hangover from pre-osboot-merge libreboot. the idea
was to distribute fsdg uboot archives
lbmk has uboot support, and releases will simply
include uboot in the main src archive like with everything else
the --nuke option in ifdtool will be used instead, to nuke
the ME regions in specific rom sets (and cbfstool will be
used to delete mrc.bin files from rom sets)
the new method being implemented is heavier on disk io, but
simplifies lbmk, and disk io could still be optimised in
the following ways:
* when copying roms from boards with ME in them, use
ifdtool --nuke to get filename.rom.new, and *move* (not copy)
filename.rom.new to the new destination (for use with tar)
* possibly modify ifdtool to make efficient use of mmap for
disk i/o; it currently loads entire roms into an allocated
buffer in memory
