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) |
