wic: add UEFI kernel as UEFI stub
Linux kernel can be compiled as UEFI stub and loaded directly with UEFI firmware without grub or other UEFI shell. Tested with wic file: bootloader --ptable gpt --timeout=0 --append="rootwait" part /boot --source bootimg-efi --sourceparams="loader=uefi-kernel" \ --ondisk sda --fstype=vfat --label bootfs \ --active --align 1024 --use-uuid part / --source rootfs --fstype=ext4 --label rootfs \ --align 1024 --exclude-path boot/ --use-label (From OE-Core rev: b18025fc8a2dad963b6f4b697e24455f2511b279) Signed-off-by: Maxim Uvarov <maxim.uvarov@linaro.org> Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
