Description Jesper Skov 2001-08-16 04:42:10 EDT
For this to work, we'd need to replace the present SETUP1 macro with
more macros like those used in the MIPS HAL. As per comment from
Mark, it may be a little hard to do properly: some platforms need to
init memory controller before MMU, others need to do it the other
way.

I suggest we use something like:

 hal_cpu_init
#ifdef CYGHWR_ARM_MMU_BEFORE_MEMC
 hal_mmu_init
 hal_memc_init
#else
 hal_memc_init
 hal_mmu_init
#endif
 hal_fpu_init
 hal_intc_init
 hal_cache_init
 hal_timer_init


There are already two platforms supporting ROMRAM startup using magic
in the SETUP1 macro.
