I'm not sure I understand what are you trying to propose here...
If you look once again on the code, there is currently only one if (cpu_is_..) {} else {}
statement currently present.
(I can remove the "if (cpu_is_omap3630())" - it indeed has no value)

Indeed, there will be some other differences...
Each time I submit a patch, I try to be as optimal as I can,
but again I'm open for suggestions...
(though I think it is optimal, e.g. 33 lines for a new running board...)
