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.

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.

Set revision to the commit hash of the v2022.10 release, and run "make
olddefconfig" for all boards to refresh the configs.

This adds U-Boot configuration for the ASUS Chromebook Flip C101,
also known as "chromebook_bob" in the U-Boot upstream defconfigs. It
uses the shared tree for the "gru" baseboard.
The config has the following diffconfig from kevin:
# chromebook_bob instead of chromebook_kevin
DEFAULT_DEVICE_TREE "rk3399-gru-kevin" -> "rk3399-gru-bob"
DEFAULT_FDT_FILE "rockchip/rk3399-gru-kevin.dtb" -> "rockchip/rk3399-gru-bob.dtb"
OF_LIST "rk3399-gru-kevin" -> "rk3399-gru-bob"
SPL_OF_LIST "rk3399-gru-kevin" -> "rk3399-gru-bob"
TARGET_CHROMEBOOK_BOB n -> y
TARGET_CHROMEBOOK_KEVIN y -> n
# Display resolution is 1280x800, and no need for the big font
VIDEO_FONT_8X16 n -> y
VIDEO_FONT_TER16X32 y -> n
VIDEO_ROCKCHIP_MAX_XRES 2400 -> 1280
VIDEO_ROCKCHIP_MAX_YRES 1600 -> 800
Untested since I don't have the bob chromebook.
