To me this seems also a cleaner solution, as any end user, that simply 
takes the u-boot sources and performs a make, would easily find the 
appropriate file to burn on his boot media.

But in that case, as the NAND image format (for instance) is 
architecture and/or SoC dependant, what do you suggest is to add 
conditionals in the Makefile that adequate the 'u-boot-nand.bin' file to 
the target SoC?
