Is this new build target really needed? Please take a look at the
recently added/renamed targets (e.g. u-boot-with-spl.bin or u-boot-img.bin).

If this does not fit, then please add a short description about this new
build target and which SoC's need it and why.

Thanks,
STefan

Hmm, this is an mkimage version of spl binary. This mkimage header is 
detected by the BootROM in spear devices for loading and booting the SPL 
binary

You mean add a short description in commit log or in README ?

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

Yes, it introduces only mkimage SPL image version. This is necessary for 
a few booting options where we absolutely require a different SPL binary 
with an mkimage header

You mean u-boot.spr can use this u-boot-spl.img. Yes, I will do that in v2
