Rockchip platform would require an explicit call to mkimage for creating bootable images which indeed specific to SoC family along with boot devices. Example of creating bootable image for rk3399 family with SD boot device as ₹ mkimage -n rk3399 -T rksd -d ./spl/u-boot-spl-dtb.bin u-boot-spl-rockchip.bin This patch would do the same think via Makefile.spl for rk3399. This would be an initial version and it can easily expand further to support other families of SoC's with variety of boot stages like TPL, SPL.
