This patch allows AP148 to boot from NOR flash. As we're using a FIT image as kernel (which includes kernel bin + DTB) we enable the MTD_SPLIT_FIT_FW kernel option, which will detect the FIT image and automatically split the "firmware" partition into 2 MTD parts (kernel + rootfs). The rootfs will then be parsed and split between rootfs + rootfs_data, as usual.
