My opinion on the whole mach-type question is "if a board needs a 
mach-type it's because it will run Linux, so its mach-type should 
eventually be in the Linux mach-type list". As I understand it, the only 
case when is not there is because U-Boot support is submitted before 
Linux mainline support. Thus I second the idea of defining it in the 
board config header file, possibly even testing for it first and if it 
already exists, throwing a #error to remind the board maintainer to 
remove the now useless define from the config file.
