Leah Rowe 59dba6cfcd merge coreboot/u-boot download logic to one script
they are fundamentally the same, in an lbmk context.

they are downloaded in the same way, and compiled in
the same way!

(Kconfig infrastructure, board-specific code, the way
submodules are used in git, etc)

~200 sloc reduction in resources/scripts

the audit begins

Alper Nebi Yasak f0236acbc6 u-boot: Increase EFI variable buffer size
Debian's signed shim allocates too many EFI variables to fit in the EFI
variable memory buffer. Normally it would then try to continue booting
in non-secure-boot mode, but its error handling throws a synchronous
abort that reboots the board, making it impossible to boot into Debian
unless one manually loads GRUB instead of shim. Increase EFI variable
buffer size to avoid triggering the bug.

Alper Nebi Yasak 7932d5fa95 u-boot: Disable environment storage
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.

Alper Nebi Yasak 8d57468ee5 u-boot: Update to v2023.01
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.

Alper Nebi Yasak 6cabcec51d u-boot: Add video damage tracking patch series
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.

Alper Nebi Yasak 38328b9394 u-boot: Set default revision to v2022.10
Set revision to the commit hash of the v2022.10 release, and run "make
olddefconfig" for all boards to refresh the configs.

Alper Nebi Yasak c798975de6 u-boot: Use a common tree
Merge all boards into a common "default" tree, currently for v2022.07.
This ends up applying the "Improve UEFI experience on DM_VIDEO" series
to everything, so refresh the configs for the new options.

Alper Nebi Yasak ff39bba2fa u-boot: Add bob chromebook 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.
