The 5441x (54410/54415/54416/54417/54418) is similar to the 532x in the same
way the 532x is similar to the 5208; it doesn't have either IPSBAR nor MBAR,
instead everything resides at a fixed address. Many of the registers common
between the 5441x and the 532x live at the same address as the 532x, but of
course the 5441x has a v4e core, cache and mmu, along with 10 uarts! 6 i2c
controllers, 4 dma capable spi controllers, usb and much more. This patch is
just a quick and dirty hack to get it booting on the twr-mcf5441x board. Its
currently nommu only (well, I havent even tried it with the mmu), It doesnt
include support for the 2 fec controllers, the ones on the 5441x are just
slightly different in some non obvious way so they dont quite work yet.
