2022-11-22build/roms: remove seabios_grubfirst logicLeah Rowe
the intended use-case scenario was one in which vga rom initialisation would be used, on desktop configurations, but without coreboot itself handling vga rom initialisation, instead leaving that task to seabios it was assumed that grub, when running on the bare metal with build option "--with-platform=coreboot" would be able to display like this, but it is not so when tested in such setups (add-on gpu with grub payload), it is necessary to extract the video bios and insert it into the coreboot rom, having coreboot handle such execution. this is beyond the scope of lbmk, in context of automated building, because we cannot reliably predict things such as PCI IDs do away with this build option entirely, for it does not serve the intended purpose. it will be necessary to run PC GRUB instead (build option --with-platform=i386-pc). PC GRUB can still read from CBFS, and you could provide it as a floppy image file inside CBFS for SeaBIOS to execute. in this setup, GRUB would function as originally intended by the seabios_withgrub option; such a configuration is referred to as "SeaGRUB" by the libreboot project, and experimentation was done with it in the past, to no avail it's better to keep things simple, in the libreboot project. simpler for users, that is

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.

2022-08-28build/roms: Rebuild cbutils module before starting coreboot buildAlper Nebi Yasak
In recent coreboot versions, running distclean started to erase the cbfstool binary we built earlier in the util/cbfstool dir via the cbutils build script call. The coreboot build puts it in a different directory, and the roms build script can't find it when trying to add payloads to the roms. This doesn't make the script fail (because set -e is stupid like that), and the build appears to succeed if you don't look close enough to see the "cbfsutil not found" error. Build the coreboot utils we want at the places we want them after calling distclean, so that we can actually use cbfsutil and avoid silently-broken roms with newer coreboot versions.

2022-08-28build/roms: Support using U-Boot as a coreboot payloadAlper Nebi Yasak
This enables embedding U-Boot into the coreboot roms as the payload. For now, the ELF file generated by enabling CONFIG_REMAKE_ELF is used, which includes the U-Boot binary and the board-specific device-tree file. It might be better to use the FIT payload support for U-Boot, but that was reportedly broken and is not tested yet. Coreboot boards can specify payload_uboot="y" in their board.cfg to enable building a rom with U-Boot as the payload, which is built from the U-Boot board with the same name. Boards can further specify a uboot_config option, to choose which board-specific config file U-Boot should be built with. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>

2022-08-28build/payload: Add helper script to build U-Boot as payloadAlper Nebi Yasak
This enables building U-Boot for boards which have config files in resources/u-boot, and copying built files that could be usable to make coreboot payloads. Right now, there is no such board in this repo. The most important file here is "u-boot.elf", which is a combination of the U-Boot binary and the appropriate device-tree file for the board. Building this needs CONFIG_REMAKE_ELF=y on the U-Boot part, and using this with CONFIG_PAYLOAD_ELF=y on the coreboot build works fine. Note that this isn't enough to make U-Boot-only releases, since low-level prerequisites like arm-trusted-firmware aren't passed in to the U-Boot build system. Coreboot builds its own copy of TF-A and sets it up on the board, so using these U-Boot builds as payloads should still work. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
