/*
 * 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 64KB and start
 * on a boundary that is a multiple of the window size):
 *
 *    0x42000000-0x4203ffff      - Internal SRAM
 *    0xf1000000-0xf100ffff      - MV64360 Registers (CONFIG_MV64X60_NEW_BASE)
 *    0xfc800000-0xfcffffff      - RTC
 *    0xff000000-0xffffffff      - Boot window, 16 MB flash
 *    0xc0000000-0xc3ffffff      - PCI I/O (second hose)
 *    0x80000000-0xbfffffff      - PCI MEM (second hose)
