 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
+	0xffc0_0000	0xffc0_ffff	PCI1/PEX1 IO	64K
+	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:
+
+	Memory Range			Device		Size
+	------------			------		----
