2023-08-29grub: all one grub.elf containing keymaps and cfgLeah Rowe
new behaviour: * grub.cfg and grubtest.cfg no longer inserted to cbfs * grub.cfg in memdisk instead * grub.cfg in memdisk defers to cbfs/grub.cfg if added (not added by default, anymore) * does not defer to grubtest.cfg even if available * only shows link to grubtest.cfg if available, as a menuentry item keymaps: if /keymap.gkb exists in cbfs, it uses that by default, but by default this isn't added. instead, it looks for a file named keymap.cfg and sources that, which then sets the keymap to one that is located under memdisk. this file is inserted for each rom, per layout. if keymap.gkb and keymap.cfg both absent, grub.cfg in memdisk shall defer to usqwerty as the default keymap grub_scan_disk: grub.cfg looks for cbfs file "scan.cfg" and sources that if found, which will be inserted with the string: set grub_scandisk=setting_goes_here (based on target.cfg, generated by build/boot/roms automatically). If no scan.cfg is found, it defaults to "both" The "background.png" file remains unchanged, and present in CBFS, used by grub.cfg if present (and it is, by default) This change actually *saves* space in CBFS, due to compression, and means that the grub.cfg is now compressed heavily. This is also safer, because now the user overrides grub.cfg by adding it, and they can still add grubtest.cfg for testing first. If they accidentally delete both configs from cbfs, Libreboot will fall back to the one in memdisk which would presumably not be deleted. This also means that lbmk can now more easily be used by other build systems, that just want the GRUB part to re-use in their own project. For example, people who want to build custom coreboot images without using Libreboot's build system. This change also *speeds* up the build process considerably, on the parts where ROM images are copied. It's less than half a second now, whereas previously it took about 30-45 seconds for ROM images to copy, because of grub.elf being re-added in each ROM via cbfstool, where compression is used; I believe the compression part is what caused slowness. Much, much faster, more versatile builds. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-08-28build/boot/roms: fix bad variable assignmentLeah Rowe
this was an oversight, in a previous commit. there was a space, between variable name and the equals sign, and then another space, so it was trying to *execute* the rom Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-08-28build/boot/roms: use the new coding styleLeah Rowe
lbmk's new style is inspired by the bsd coding styles: top-down logic, main simplified to a skeleton showing overall program structure, variables well-defined, rigorous (yet deceptively simple) error checking. this was attempted before, but caused problems; coreboot wasn't being cleaned properly, and rather than audit it, i simply reverted this back to the old style. this is actually attempt number 5, because i made 3 more attempts between then and this one. i've build-tested this using "./build boot roms all" (which is what b0rked on the first attempt, months ago). it should be stable(tm). the code is much nicer to read / work on now. this is the beating heart of lbmk. get this script wrong, and you break all of libreboot.
