 +==== Functional Specs ====
 +
 +=== CPU Address Decoding ===
 +Sheeva CPU core has 13 address windows:
 +  * 4x for CPU access to DRAM CS
 +  * 1x for CPU access to internal registers
 +  * 8x configurable for CPU access to remaining chip resources
 +== DRAM Windows ==
 +  * 8-bit BASE & SIZE registers
 +  * BASE corresponds to address bits [31:24]
 +  * Min. SIZE (0x01) = 16MB; max. SIZE (0xFF) = 4GB
 +  * SIZE is a mask; only 8 legal values (0x01, 0x03, 0x07, 0x0F, etc.)
 +== Register Window ==
 +  * Fixed SIZE of 1MB
 +  * BASE register
 +== Configurable Windows ==
 +  * 16-bit BASE & SIZE registers
 +  * BASE corresponds to address bits [31:16]
 +  * Min. SIZE (0x0001) = 64KB; max. SIZE (0xFFFF) = 4GB
 +  * SIZE is a mask; 16 legal values
 +=== SATA Address Decoding ===
 +  * 4x address windows
 +  * SDRAM and PCIe interface access
 +=== GbE Address Decoding ===
 +  * 6x address windows
 +  * SDRAM interface access only
 +=== USB Address Decoding ===
 +  * 4x address windows per USB port
 +  * SDRAM interface access only
 +=== SDIO Address Decoding ===
 +  * 4x programmable address windows
 +  * SDRAM and PCIe interface access
 +=== Default Address Map (p.41) ===

 +Wish I found this earlier (kirkwood/cpu.c): Linux expects the internal registers to be at 0xF1000000
 +
 +Internal registers base address is set in register offset 0x20080 (arch-kirkwood/kirkwood.h): i.e. 0xF1020080 = 0xF1000000
