Thus, this is consistent with a flash base address 0xfff80000. + +The placement at the end is to be consistent with reset behavior, +where the processor itself initially uses this bus to load the branch +vector and start running. + +On-Chip Memory +-------------- + +0xf4000000 - 0xf4000fff + +The 405GPr includes a 4K on-chip memory that can be placed however +software chooses. I choose to place the memory at this address, to +keep it out of the cachable areas. + + +Memory Bank 1 -- SystemACE Controller +------------------------------------- + +0xf0000000 - 0xf00fffff + +The SystemACE chip is along on peripheral bank CS#1. We don't need +much space, but 1Meg is the smallest we can configure the chip to +allocate. We need it far away from the flash region, because this +region is set to be non-cached. + + +Internal Peripherals +-------------------- + +0xef600300 - 0xef6008ff + +These are scattered various peripherals internal to the PPC405GPr +chip. + +SDRAM +----- + +0x00000000 - 0x07ffffff (128 MBytes) |
