2023-02-14u-boot: Update to v2023.01Alper Nebi Yasak
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.

2022-12-10u-boot: Add video damage tracking patch seriesAlper Nebi Yasak
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.

2022-12-10u-boot: Set default revision to v2022.10Alper Nebi Yasak

2022-12-10u-boot: Use a common treeAlper Nebi Yasak
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. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2022-08-28u-boot: Add kevin chromebook configsAlper Nebi Yasak
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 VIDEO_FONT_TER16X32 n -> y Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
