[PATCH] ppc32: add support for Marvell EV64360BP board

This patch adds support for Marvell EV64360BP board.  So far, it supports
mpsc serial console, gigabit ethernet, jffs2 root filesystem, etc.  Other
device support, like watchdog, RTC, will be added later.

/*
* 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)
