Log Message:
Handling CFE addresses in 64-bit mode.  From the comment in the code:

 * We do this KSEG0 to PHYS to KSEG0 dance if running 64-bit because
 * CFE passes in parameters as 32-bit addresses.  When used as a 64-bit
 * address these CFE parameters are in user (XKUSEG) space and can't be
 * accessed!  Convert these to a physical address and and then to the
 * proper KSEG0 address so we can use them in the kernel.

Allows SBMIPS to starting booting with a 64-bit kernel.
