I see. It'd be nice to put some of the above information in the U-Boot commit logs to give people an idea about what's going on without having to use google, etc. I haven't looked at the code differences between the sp3xx boards, but you might be able to use 1 common board file/header file to support them all. For example, take a look at the M5475AFE_config rule in U-Boot's ./Makefile. Some extra code in the Makefile and some #ifdefs in the sp3xx code might accommodate all 3 boards.
