Mark A. Greer f4c6cc8d1e [PATCH] ppc32: katana updates 
Update the katana platform support code:
- if booted as zImage, pass mem size in via bi_req from bootwrapper
- if booted as uImage, get mem size from bd_info passed in from u-boot
- add support for 82544 present on katana 752i's
- set cacheline size on pci devices
- some minor fixups

* 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 64 KB and start
* on a boundary that is a multiple of the window size):
*
* 0xff800000-0xffffffff - Boot window
* 0xf8400000-0xf843ffff - Internal SRAM
* 0xf8200000-0xf83fffff - CPLD
* 0xf8100000-0xf810ffff - MV64360 Registers (CONFIG_MV64X60_NEW_BASE)
* 0xf8000000-0xf80fffff - Socketed FLASH
* 0xe0000000-0xefffffff - Soldered FLASH
* 0xc0000000-0xc3ffffff - PCI I/O (second hose)
* 0x80000000-0xbfffffff - PCI MEM (second hose)
