Yes, I remember this from the SPEAr600. I introduced a new build target
for this: u-boot.spr. Take a look at the commit:
94aebe6cc3111c7c9e3cd1311cc9793d01cc3ded
Makefile: Add u-boot.spr build target (SPEAr)
On x600 (SPEAr600) U-Boot is appended to U-Boot SPL. Both images are
created using mkimage (crc etc), so that the ROM bootloader can check
its integrity. Padding needs to be done to the SPL image (with
mkimage header) and not the binary. Otherwise the resulting image
which is loaded/copied by the ROM bootloader to SRAM doesn't fit.
The resulting image containing both U-Boot images is called u-boot.spr.
Or does your patch "only" introduce the mkimage SPL image version?
Then please consolidate this with the u-boot.spr build target.
Thanks,
Stefan
