    mpc8641: Support 36-bit physical addressing · 3111d32c

    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.
