2023-02-14u-boot: Disable environment storageAlper Nebi Yasak
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.

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.

2022-12-31u-boot: Enable USB_EHCI_EXYNOS on peach boardsAlper Nebi Yasak
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.

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
Set revision to the commit hash of the v2022.10 release, and run "make olddefconfig" for all boards to refresh the configs. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
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>
2022-08-29u-boot: Add peach pi chromebook configsAlper Nebi Yasak
This adds U-Boot configuration for the Samsung Chromebook 2 13", also known as "peach-pi" in the U-Boot upstream defconfigs. It uses the shared tree for the "peach" 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 peach pi chromebook. Note the there doesn't seem to be any coreboot support for this chromebook. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
