Why would you ever want to compile this into U-Boot at all?  Then any
changes you need to make mean compiling and installing a new U-Boot,
which is something you normally don't want to do.

U-Boot is perfectly able to import such settings from text files (or
text blobs stored somewhere, even attached to the U-Boot image, if you
want), so just use the text files separately, instead of hard
compiling them into the code.

Best regards,

Wolfgang Denk
