That won't make too much sense. You won't run the same binary on both pxa2xx and 
pxa3xx ... ever. Increasing the bootloader size only because you want to avoid 
ifdef makes no sense either.

There are other ifdefs in that driver that need to go away (will in further 
patches), this one is the least harmful one.
