20 * The MV64360 has 2 PCI buses each with 1 window from the CPU bus to
21 * PCI I/O space and 4 windows from the CPU bus to PCI MEM space.
22 * We'll only use one PCI MEM window on each PCI bus.
24 * This is the CPU physical memory map (windows must be at least 64K and start
25 * on a boundary that is a multiple of the window size):
27 * 0x80000000-0x8fffffff - PCI 0 MEM
28 * 0xa0000000-0xafffffff - PCI 1 MEM
29 * 0xc0000000-0xc0ffffff - PCI 0 I/O
30 * 0xc1000000-0xc1ffffff - PCI 1 I/O
32 * 0xf1000000-0xf100ffff - MV64360 Registers
33 * 0xf1010000-0xfb9fffff - HOLE
34 * 0xfbfa0000-0xfbfaffff - TBEN
35 * 0xfbf00000-0xfbfbffff - NEXUS
36 * 0xfbfc0000-0xfbffffff - Internal SRAM
37 * 0xfc000000-0xffffffff - Boot window
