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.

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.

The display driver on the veyron boards needs reset drivers, more specifically RESET_ROCKCHIP. This is enabled by default depending on DM_RESET, which an upstream commit enables for veyron_jerry claiming it fixes the display [1]. Enable it also in our configs, but for other veyrons as well.

Add a U-Boot payload build for the QEMU AArch64 virtual machine. The config is same as upstream "qemu-arm64" defconfig, but SYS_TEXT_BASE is set to 0x50000000 so that it doesn't conflict with coreboot. QEMU auto-generates and passes a device-tree file to U-Boot at runtime, there's no compile-time canonical version, so there's no need to set REMAKE_ELF or OF_EMBED. It's not immediately obvious if QEMU-specific drivers are available to support display output, but most coreboot integration is unavailable (depends on x86) and entire video subsystem is disabled in the U-Boot upstream defconfig.

Add a U-Boot build for the qemu_x86_12mb board. The config is a copy of the upstream "coreboot" defconfig, but with OF_EMBED=y. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
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. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
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>
