/*
* The MV64360 has 2 PCI buses each with 1 window from the CPU bus to
* PCI I/O space and 4 windows from the CPU bus to PCI MEM space.
* We'll only use one PCI MEM window on each PCI bus.
*
* This is the CPU physical memory map (windows must be at least 64K and start
* on a boundary that is a multiple of the window size):
*
* 0x80000000-0x8fffffff - PCI 0 MEM
* 0xa0000000-0xafffffff - PCI 1 MEM
* 0xc0000000-0xc0ffffff - PCI 0 I/O
* 0xc1000000-0xc1ffffff - PCI 1 I/O
* 0xf1000000-0xf100ffff - MV64360 Registers
* 0xf1010000-0xfb9fffff - HOLE
* 0xfbfa0000-0xfbfaffff - TBEN
* 0xfbf00000-0xfbfbffff - NEXUS
* 0xfbfc0000-0xfbffffff - Internal SRAM
* 0xfc000000-0xffffffff - Boot window
