4. Memory Map
-------------
+NOTE: RIO and PCI are mutually exclusive, so they share an address
+
+For 32-bit u-boot, devices are mapped so that the virtual address ==
+the physical address, and the map looks liks this:
Memory Range Device Size
------------ ------ ----
0x0000_0000 0x7fff_ffff DDR 2G
+ 0x8000_0000 0x9fff_ffff RIO MEM 512M
0x8000_0000 0x9fff_ffff PCI1/PEX1 MEM 512M
- 0xa000_0000 0xafff_ffff PCI2/PEX2 MEM 512M
- 0xf800_0000 0xf80f_ffff CCSR 1M
- 0xf810_0000 0xf81f_ffff PIXIS 1M
+ 0xa000_0000 0xbfff_ffff PCI2/PEX2 MEM 512M
+ 0xffe0_0000 0xffef_ffff CCSR 1M
+ 0xffdf_0000 0xffdf_7fff PIXIS 8K
+ 0xffdf_8000 0xffdf_ffff CF 8K
0xf840_0000 0xf840_3fff Stack space 32K
- 0xe200_0000 0xe2ff_ffff PCI1/PEX1 IO 16M
- 0xe300_0000 0xe3ff_ffff PCI2/PEX2 IO 16M
- 0xfe00_0000 0xfeff_ffff Flash(alternate)16M
- 0xff00_0000 0xffff_ffff Flash(boot bank)16M

+ 0xffc1_0000 0xffc1_ffff PCI2/PEX2 IO 64K
+ 0xef80_0000 0xefff_ffff Flash 8M
+
+For 36-bit-enabled u-boot, the virtual map is the same as for 32-bit.
+However, the physical map is altered to reside in 36-bit space, as follows.
+Addresses are no longer mapped with VA == PA. All accesses from
+software use the VA; the PA is only used for setting up windows
+and mappings. Note that the low 32 bits are the same as the VA above;
+only the top 4 bits vary:
