This patch creates a memory map with all the devices in 36-bit physical space, in addition to the 32-bit map. The CCSR relocation is moved (again, sorry) to allow for the physical address to be 36 bits - this requires translation to be enabled. With 36-bit physical addressing enabled, we are no longer running with VA=PA translations. This means we have to distinguish between the two in the config file. The existing region name is used to indicate the virtual address, and a _PHYS variety is created to represent the physical address.
Large physical addressing is not enabled by default. Set CONFIG_PHYS_64BIT in the config file to turn this on.

Can we add something to the top level Makefile like the following:
MPC8641HPCN_36BIT_config \ MPC8641HPCN_config: unconfig @mkdir -p $(obj)include @if [ "$(findstring _36BIT_,$@)" ] ; then \ $(XECHO) -n "... I Rock " ; \ echo "#define CONFIG_PHYS_64BIT" >>$(obj)include/ config.h ;\ fi ; @$(MKCONFIG) -a MPC8641HPCN ppc mpc86xx mpc8641hpcn freescale
(also add this to MAKEALL)
The name could be better.
