consolidate u-boot/seabios/coreboot build scripts
See file: resources/scripts/build/defconfig/for It is based on: resources/scripts/build/payload/u-boot The u-boot payload script has been deleted, as has the seabios payload script; the build/boot/roms logic has been heavily simplified too, by removing the logic for building of elf files based on defconfig. SeaBIOS, U-Boot and coreboot all use defconfig-type infrastructure for their build systems, and they are fundamentally the *same* in how to compile each codebase, at least in an lbmk context, regardless of actual (and very huge) differences in these codebases. Several hundred sources-lines of code have been eliminated by this change, drastically simplifying everything; U-Boot payload compiling also now errors out when a single build fails, instead of continuing. Also: build/boot/roms no longer re-compiles a coreboot target that was already compiled, which is the same behaviour observed for payloads. (this means you must now manually delete a target, when you wish to re-build it; the build/boot/roms logic now more or less just runs cbfstool; blobutil is handled from build/defconfig/for) ALSO: Since crossgcc is now handled by build/defconfig/for, not build/boot/roms, standalone compiling of u-boot is now possible. This has been tested. You compile it like so: ./build defconfig for u-boot or specific trees, e.g. ./build defconfig for u-boot default One other consequence of this patch is that re-building the same ROM image is now much faster, because the same builds are re-used unless deleted. This could be useful when testing grub.cfg changes, for example, if that's all you change. With things like ccache used (not yet used robustly in lbmk), this could speed things up more, depending on the codebase. This patch demonstrates the raw power of lbmk; it is a very simple and highly efficient build system, and now much more so! Signed-off-by: Leah Rowe <leah@libreboot.org>
