__ASSEMBLY__ already be used.
__PRE_SDRAM__ maybe good, but if we define USE_DCACHE = 1, __ROMCC__is equal to __PRE_SDRAM___ it mean code will be compiled by gcc instead of romcc.

Is there any reason we need two different ways to do it? If both of
them
are as good, can we drop one and support just the other?
BTW, after reading your patch, I found there is very little difference
between auto.c and cache_as_ram_auto.c. Most of the differences are in the included files, can we merge auto.c and cache_as_ram_auto.c?
Talking about merging auto.c and cache_as_ram_auto.c, you are using #define __ROMCC__ to choose different definitions of device_t. I don't thing it is the right way to do it. Instead, we should use another macro for this (__ASSEMBLY__ or __PRE_SDRAM__)?
