I would like to see RCW in a separated block.

It is not your original words. Yours was "To form a NAND image, append
u-boot-with-spl.bin after PBL_0x3_0x07_1333_nand.bin and flash to the beginning
of NAND.". I try to make the message generic. A proper nand boot RCW means the
RCW should contains PBI commands to set bootloc and block copy the image. Since
RCW is not in the scope of u-boot, I cannot refer to any specific file.

Do you want to include an RCW file into u-boot, like those for powerpc boards?

That can be an additional patch when you have it.
