When Grub2 is build it is configured only for one boot set-up, BIOS Legacy, EFI 32 bit or EFI 64 bit. It can not deal with several boot set-up on the same image. This patch allows to build Grub2 for different configurations simultaneously. To cover Grub2 configuration of legacy BIOS platforms (32-bit), 32-bit EFI BIOS and 64-bit EFI BIOS in the same build, multi-build system felt much more reasonable to just extend the grub2 package into 3 packages. We can no longer use autotools-package as a consequence of this multi-build, and we have to resort to generic-package and a partial duplication of the autotools-infra. Grub2 was already using custom option like --prefix or --exec-prefix so this won't add much more weirdness. We use a GRUB2_TUPLES list to describe all the configurations selected. For each boot case described in the GRUB2_TUPLES list, it configures and builds Grub2 in a separate folder named build-$(tuple). We use a foreach loop to make actions on each tuple selected. We have to separate the BR2_TARGET_GRUB2_BUILTIN_MODULES and the BR2_TARGET_GRUB2_BUILTIN_CONFIG for each BIOS or EFI boot cases.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
