wic: allow multiple /boot partitions with different content
It can be useful to have multiple partitions with '--source bootimg-partition' but different content. E.g. for TI AM335x, one boot partition can contain an first stage bootloader ("MLO"), while the real bootloader and kernel plus devicetree are in another one. Patch allows to specify multiple IMAGE_BOOT_FILES with optional "_label-XXX" or "_uuid-XXX" overrides. E.g. with this patch, a .wks file with | part --source bootimg-partition ... --label=mlo --active | part --source bootimg-partition ... --label=boot0 | part --source bootimg-partition ... --label=boot1 and a recipe with | IMAGE_BOOT_FILES_label-mlo = "\ | MLO-${MACHINE}.img;MLO \ | " | | IMAGE_BOOT_FILES_label-boot0 = "\ | u-boot-${MACHINE}.img;u-boot.img \ | zImage \ | " | | IMAGE_BOOT_FILES_label-boot1 = "${IMAGE_BOOT_FILES_label-boot0}" | | WICVARS += " \ | IMAGE_BOOT_FILES_label-mlo \ | IMAGE_BOOT_FILES_label-boot0 \ | IMAGE_BOOT_FILES_label-boot1 \ | " is possible. It will create one partition with the MLO and two redundant ones with the uboot + kernel. Signed-off-by: Enrico Scholz <enrico.scholz@ensc.de> Signed-off-by: Ross Burton <ross.burton@intel.com>
