Physical Mapping
| Address | Size | Description |
|---|---|---|
| c000xxxx | 10000 | Initial "Kernel" (bootloader, not real kernel), mapped L2-Cache? |
| c8xxxxxx | 1000000 | memory mapped NAND flash (RO, 1:1, no OoB(ECC)) |
| c9xxxxxx | 1000000 | ??? |
| d0xxxxxx | 1000000 | PCI config space. Device number etc. is encoded in address, as usual |
| e0000000 | ??? | Host-Bridge |
| ea000000 | ??? | PCI-to-PCI bridge |
| ec800000 | ??? | GPU |
