This commit enables the arm-uboot, arm-efi and aarch64-efi grub2 platforms in Buildroot. With the uboot platform, the grub2 image gets built as a u-boot image and is loaded from u-boot through a regular "bootm". The only requirement from the u-boot side in order to allow this is that u-boot is built with CONFIG_API enabled. CONFIG_API seems to not be enabled by default in most in-tree configurations, however, it seems to be available for quite some time now. So it might be possible to use this even on older u-boot versions. This is available only for arm (32-bit). With the efi platform, grub2 gets built as an EFI executable. This allows EFI firmware to find and load it similarly as it can be done for x86_64. Also, since u-boot v2016.05, u-boot is able to load and boot an EFI executable, so the uboot efi platform can also be used from u-boot in recent versions. This has been enabled (mostly) by default for ARM u-boot. efi platform is available for both arm and aarch64.
