15 * The MV64x60 has 2 PCI buses each with 1 window from the CPU bus to
16 * PCI I/O space and 4 windows from the CPU bus to PCI MEM space.
17 * We'll only use one PCI MEM window on each PCI bus.
19 * This is the CPU physical memory map (windows must be at least 1MB and start
20 * on a boundary that is a multiple of the window size):
22 * 0xfc000000-0xffffffff - External FLASH on device module
23 * 0xfbf00000-0xfbffffff - Embedded (on board) FLASH
24 * 0xfbe00000-0xfbefffff - GT64260 Registers (preferably)
25 * but really a config option
26 * 0xfbd00000-0xfbdfffff - External SRAM on device module
27 * 0xfbc00000-0xfbcfffff - TODC chip on device module
28 * 0xfbb00000-0xfbbfffff - External UART on device module
29 * 0xa2000000-0xfbafffff - <hole>
30 * 0xa1000000-0xa1ffffff - PCI 1 I/O (defined in gt64260.h)
31 * 0xa0000000-0xa0ffffff - PCI 0 I/O (defined in gt64260.h)
32 * 0x90000000-0x9fffffff - PCI 1 MEM (defined in gt64260.h)
33 * 0x80000000-0x8fffffff - PCI 0 MEM (defined in gt64260.h)
