make GRUB multi-tree and re-add xhci patches Re-add xHCI only on haswell and broadwell machines, where they are needed. Otherwise, keep the same GRUB code. The xHCI patches were removed because they caused issues on Sandybridge-based Dell Latitude laptops. See: https://codeberg.org/libreboot/lbmk/issues/216 The issue was not reported elsewhere, including on the Haswell/Broadwell hardware where they are needed, but the build system could only build one version of GRUB. The older machines do not need xHCI patches, because they either do not have xHCI patches, or work (in GRUB) because they're in EHCI mode when running the payload. So, the problem is that we need the xHCI patches for GRUB on Haswell/Broadwell hardware, but the patches break Sandybridge hardware, and we only had the one build of GRUB. To mitigate this problem, the build system now supports building multiple revisions of GRUB, with different patches, and each given coreboot target can say which GRUB tree to use by setting this in target.cfg: grubtree="xhci" In the above example, the "xhci" tree would be used. Some generic GRUB config has been moved to config/data/grub/ and config/grub/ now looks like config/coreboot/ - also, the grub.cfg file (named "payload" in each tree) is copied to the GRUB source tree as ".config", then added to GRUB's memdisk in the same way, as grub.cfg. Several other design changes had to be made because of this: * grub.cfg in memdisk no longer automatically jumps to one in CBFS, but now shows a menuentry for it if available * Certain commands in script/trees are disabled for GRUB, such as config make commands. gnulib is now defined in config/submodule/grub/, instead of config/git/grub - and this mitigates an existing bug where downloading gnulib first would make grub no longer possible to download in lbmk. The coreboot option CONFIG_FINALIZE_USB_ROUTE_XHCI has been re-enabled on: Dell OptiPlex 9020 MT, Dell OptiPlex 9020 SFF, Lenovo ThinkPad T440p and Lenovo ThinkPad W541 - now USB should work again in GRUB. The GRUB payload has been re-enabled on HP EliteBook 820 G2. This change will enable per-board GRUB optimisation in the future. For example, we hardcode what partitions and LVMs GRUB scans because * is slow on ICH7-based machines, due to GRUB's design. On other machines, * is reasonably fast, for automatically enumerating the list of devices for boot. Use of * (and other wildcards) could enable our GRUB payload to automatically boot more distros, with minimal fuss. This can be done at a later date, in subsequent revisions.

grub/target.cfg: move --disable-werror i meant to push it in configure args, not bootstrap Signed-off-by: Leah Rowe <leah@libreboot.org> 2024-01-21 05:43:11 +00:00			`bootstrapargs="--gnulib-srcdir=gnulib/ --no-git"`

update/trees: support custom make/autogen argument this is now used in grub, for the FS_PAYLOAD_MODULES option in the make command lbmk should generalise as much logic as possible. in some parts of it, logic is hurrently hardcoded, specific to a given project that lbmk uses, but lbmk is essentially a source-based package manager, like what you might find on a small linux distro, so we need to try to be as generic as possible. lbmk is the "build system of build systems", so it has to work generically with as many of them as possible Signed-off-by: Leah Rowe <leah@libreboot.org> 2023-12-30 19:25:26 +00:00			`makeargs="FS_PAYLOAD_MODULES=\"\""`
