/*
 * 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
