hi jamey,

Wo thought it would be nice if we could had a modulat structure for the architectures and processor. All the bootldr architecture depend on SA1100 and they seems to split in to each plaform file (skiff/sa1100) with addition of PXA250 etc tjhe code might become messy. Does the following make any attempt to solve this?

<Makefile>
..
ifeq ($(CONFIG_ARCH), gator)
  BOOTO = boot-sa.o mmu-strongarm.o
  ARCH_FLAGS=-DARCH_GATOR
endif
ifeq ($(CONFIG_ARCH), h3900)
  BOOTO = boot-sa.o mmu-strongarm.o
  ARCH_DEFS += -DCONFIG_H3900
..

<boot-sa.s>
..

#ifdef CONFIG_PXA250
# include "pxa250.h"
#else
# include "sa1100.h"
#endif
..

the registers in the code will go as REGNAME_REG instead of <ARCH>_RERGNAME_REG . Some non-common code can be put in <boot-sa<platform>.s>.

regards,
vaibhav
