There are cases to want a synthetic information whether the legacy BIOS or U-Boot boot scheme, or the EFI boot scheme, are enabled, without resorting to testing all and each platforms. This is already the cae in grub2 itself, for the configuration of the BIOS/U-Boot boot partition, and builtin modules and configuration on one hand, and the EFI builtin modules and configuraiton on the other hand. It is also the case for mender-grubenv, which will want to know if either or both are enabled, but without having to resort to testing all the cases. Add two new symbols, that each represent those conditions: * BR2_TARGET_GRUB2_HAS_LEGACY_BOOT * BR2_TARGET_GRUB2_HAS_EFI_BOOT Each target selects the appropriate bool, which makes it much more simple for other packages such as mender-grubenv to check if grub legacy or EFI is selected. And of course, we also make use of those symbols in grub2 itself, to simplify the conditions for showing.hiding legacy and EFI options. Additionally (but that does not merit being in its own patch), add a comment on the closing 'endif' for the EFI part.

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
