forked from openkylin/platform_build
Allow building recovery as boot.
With BOARD_USES_RECOVERY_AS_BOOT = true, we skip building the
non-ramdisk boot.img but building the recovery image as boot.img. It
contains recovery's ramdisk (e.g. with /sbin/recovery). It depends on
the bootloader parameter (skip_initramfs) to determine the actual mode
to boot into.
