This adds U-Boot configuration for a few white-label chromebooks, known
as "chromebook_jerry" in the U-Boot upstream defconfigs. It uses the
shared tree for the "veyron" baseboard. The config is almost the same as
upstream defconfig, but with REMAKE_ELF and POSITION_INDEPENDENT
enabled.
Untested since I don't have any of the veyron jerry chromebooks.

This adds U-Boot configuration for the ASUS Chromebook Flip C100PA, also
known as "chromebook_minnie" in the U-Boot upstream defconfigs. It uses
the shared tree for the "veyron" baseboard. The config is almost the
same as upstream defconfig, but with REMAKE_ELF and POSITION_INDEPENDENT
enabled.
Untested since I don't have the veyron minnie chromebook.

This adds U-Boot configuration for the ASUS Chromebook C201PA, also
known as "chromebook_speedy" in the U-Boot upstream defconfigs. Also
adds a shared "veyron" board directory to share with others having the
same baseboard. The config is almost the same as upstream defconfig, but
with REMAKE_ELF and POSITION_INDEPENDENT enabled.
Untested since I don't have the veyron speedy chromebook.

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.

This adds U-Boot configuration for the Samsung Chromebook Plus (v1),
also known as "chromebook_kevin" in the U-Boot upstream defconfigs. Also
adds a shared "gru" board directory to share with others having the same
baseboard.
It uses v2022.07 with some quality-of-life patches. The first one is a
clock adjustment to match coreboot clocks for the video output, the
second one is a series about text cursor support and larger fonts. These
are because the display has a high resolution of 2400x1600 at 12.3".
The config has the following diffconfig from the upstream defconfig for
this board:
# For chainloading from depthcharge like a payload (RW_LEGACY).
# Not everything might be necessary, but didn't test without these.
INIT_SP_RELATIVE n -> y
LNX_KRNL_IMG_TEXT_OFFSET_BASE 0x00200000 -> 0x18000000
POSITION_INDEPENDENT n -> y
SYS_TEXT_BASE 0x00200000 -> 0x18000000
+SYS_INIT_SP_BSS_OFFSET 524288
# Higher speeds for eMMC
MMC_HS200_SUPPORT n -> y
MMC_HS400_ES_SUPPORT n -> y
MMC_HS400_SUPPORT n -> y
MMC_IO_VOLTAGE n -> y
MMC_SDHCI_SDMA n -> y
MMC_SPEED_MODE_SET n -> y
+MMC_UHS_SUPPORT y
# Build the u-boot.elf to use as a payload
REMAKE_ELF n -> y
# Slightly faster video output
VIDEO_COPY n -> y
# Larger fonts per the applied series
VIDEO_FONT_8X16 y -> n

Add a 'v2022.07' pseudo-board for the U-Boot download script with the
default blobs list, and mark the version as supported in u-boot-libre
release script.

Boards may want to specify a board-specific U-Boot revision. At the very
least, pseudo-boards for u-boot-libre releases will need to specify their
U-Boot versions somehow.
Copy the existing mechanism from download/coreboot for specifying
build info with board.cfg files. Specify the commit hash for the
'v2021.07' pseudo-board, and 'master' as the default.

The U-Boot download script is designed to help with releasing
u-boot-libre and it can only prepare a generic U-Boot v2021.07 tree.
However, we will need to build board-specific versions of U-Boot to be
able to use it as a coreboot payload effectively.
As a first step toward that, make the download script prepare per-board
copies of U-Boot v2021.07. Then, add a 'v2021.07' pseudo-board for the
u-boot-libre release script to work on.
The u-boot-libre deblob script hash ends up chaning due to copying my
author attribution from the download script, update its hash.

Once the tarball are released, it will enable distributions to use
these tarballs to produce deblobbed u-boot packages.
Note that the produced tarball is not reproducible yet. Because of
that it has to be trusted.
During a release, it's a good idea to sign the uncompressed tarball as
the various compression formats and associated tools make different
tradeoffs.
For instance with xz, xz -9e tends to compress really well with the
the most used xz[1] implementation, and most GNU/Linux users probably
already have it installed, but and the drawbacks is that the format is
very fragile[2].
The lzip format is more suited for long term archiving but its most
packaged implementation[3] is less likely to be already installed by
users than more well known formats like xz, bzip2 or gzip.
Being able to add more compression formats after the release is also
useful, for instance to accommodate different build systems or use
cases (like being able to build u-boot with less dependencies in
distributions like Guix, or building u-boot directly on devices which
don't have enough RAM for xz for instance).
