  17  * The MV64360 has 2 PCI buses each with 1 window from the CPU bus to
  18  * PCI I/O space and 4 windows from the CPU bus to PCI MEM space.
  19  * We'll only use one PCI MEM window on each PCI bus.
  20  *
  21  * This is the CPU physical memory map (windows must be at least 64 KB and start
  22  * on a boundary that is a multiple of the window size):
  23  *
  24  *    0xff800000-0xffffffff      - Boot window
  25  *    0xf8400000-0xf843ffff      - Internal SRAM
  26  *    0xf8200000-0xf83fffff      - CPLD
  27  *    0xf8100000-0xf810ffff      - MV64360 Registers (CONFIG_MV64X60_NEW_BASE)
  28  *    0xf8000000-0xf80fffff      - Socketed FLASH
  29  *    0xe0000000-0xefffffff      - Soldered FLASH
  30  *    0xc0000000-0xc3ffffff      - PCI I/O (second hose)
  31  *    0x80000000-0xbfffffff      - PCI MEM (second hose)
