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.

    rk3399 may have TPL like other SoCs, for there will be image types:

SPL+u-boot.bin

SPL+u-boot.itb

TPL+SPL+u-boot.itb

Seems this patch and 9/9 of this patch set only cover SPL+u-boot.itb?

Is it possible to make it more generic?


Thanks,

- Kever

Yes, I have watched your TPL changes. and we can extend this to
support TPL to make combination of all images.
