merge coreboot/u-boot download logic to one script they are fundamentally the same, in an lbmk context. they are downloaded in the same way, and compiled in the same way! (Kconfig infrastructure, board-specific code, the way submodules are used in git, etc) ~200 sloc reduction in resources/scripts the audit begins Signed-off-by: Leah Rowe <leah@libreboot.org> 2023-08-16 20:34:21 +00:00			`tree="default"`

build/boot/roms: Support removing microcode From now on, the following rules are available for all mainboards, in resources/coreboot/boardname/board.cfg: * blobs_required="n" or "y" * microcode_required="n" or "y" The blobs setting, if set to "n", simply renames filename.rom to filename_noblobs.rom. The microcode setting, if set to "n", copies the ROM (with or without _noblobs) to filename_nomicrocode.rom (if blobs="n", it would be filename_noblobs_nomicrocode.rom). Where "nomicrocode" is set, ROMs with microcode will still be provided by lbmk and in relesase, but ROMs will also be provided alongside it that lacks any microcode updates. If the original ROM already lacks microcode updates, then the original ROM will be renamed to include "nomicrocode" in the name. This is done on images for ARM platforms, for instance, where microcode is never used whatsoever. Example filenames now generated: seabios_e6400_4mb_libgfxinit_corebootfb_noblobs_nomicrocode.rom seabios_e6400_4mb_libgfxinit_corebootfb_noblobs.rom seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak_nomicrocode.rom seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak.rom uboot_payload_gru_kevin_libgfxinit_corebootfb_noblobs_nomicrocode.rom A vocal minority of people were not happy with some of the changes made in Libreboot last year, including on existing supported hardware from before those changes were made. I did this before the last release, out of respect: https://libreboot.org/news/gm45microcode.html (re-add mitigations for no-microcode setup on GM45) This new change is done as an further, extended courtesy. Tested and works fine. (testing using cbfstool-print) Actual Libreboot policy about binary blobs is nuanced. See: https://libreboot.org/news/policy.html (reduction policy) and: https://libreboot.org/freedom-status.html (implementation) Well, the status page talks about descriptor vs non-descriptor on Intel platforms, and where me_cleaner is used (on platforms that need Intel ME firmware), it regards the descriptored setups to be blob-free if coreboot does not require binary blobs. In this paradigm, microcode updates are not considered to be binary blobs, because they aren't technically software, they're more like config files that just turn certain features on or off within the CPU. However, for lbmk purposes, "noblobs" means that, after the ROM is fully ready to flash on the chip, there will be no blobs in it (except microcode). So for example, an X200 that does not require ME firmware is considered blob-free under this paradigm, even though Libreboot policy regards X230 as equally libre when me_cleaner is used; in this setup, ROMs will not contain "blobfree" in the filename, for X230 (as one example).
