Sorry if I miss anything, but
what happens if I build an uImage just for Rainier (not enabling other 
platforms in the kernel config) and then start it on Canyonlands for 
example?
They both use PowerPC_44x_simple stuff and looks like now we claim that 
all these "simple" boards are compatible. So, board check always passes, 
although Canyonlands support is actually disabled (CONFIG_460EX = n; 
CONFIG_PPC4xx_PCI_EXPRESS = n). It's not critical, but I just thought we 
might also remove the platform-specific options from 
arch/powerpc/platforms/44x/Kconfig for these boards at all. Just enable 
all board-specific stuff under "config PPC44x_SIMPLE".
Otherwise we probably should have a configurable char *board[] array.

Thanks,
Valentine.
