Look in the file: > hal/arm/edb7xxx/current/include/hal_platform_setup.h Why was it done this way, and not with a more explicit ROMRAM startup type? If you have a separate startup type it is more under user control. Anyway, you can also refer to the way the mips vrc4373 or sh edk7708 do it, which use an explicit ROMRAM startup.
