1 JSE Configuration Details
3 Memory Bank 0 -- Flash chip
4 ---------------------------
6 0xfff00000 - 0xffffffff
8 The flash chip is really only 512Kbytes, but the high address bit of
9 the 1Meg region is ignored, so the flash is replicated through the
10 region. Thus, this is consistent with a flash base address 0xfff80000.
12 The placement at the end is to be consistent with reset behavior,
13 where the processor itself initially uses this bus to load the branch
14 vector and start running.
19 0xf4000000 - 0xf4000fff
21 The 405GPr includes a 4K on-chip memory that can be placed however
22 software chooses. I choose to place the memory at this address, to
23 keep it out of the cachable areas.
26 Memory Bank 1 -- SystemACE Controller
27 -------------------------------------
29 0xf0000000 - 0xf00fffff
31 The SystemACE chip is along on peripheral bank CS#1. We don't need
32 much space, but 1Meg is the smallest we can configure the chip to
33 allocate. We need it far away from the flash region, because this
34 region is set to be non-cached.
40 0xef600300 - 0xef6008ff
42 These are scattered various peripherals internal to the PPC405GPr
48 0x00000000 - 0x07ffffff (128 MBytes)
