I'm sure this is a dumb question due to the fact that my grasp of the
problem is less than acceptable...
Can remapped addresses (namely CPU_remap_addr) be used for the call
to add_memory_region()? That would allow the address for DRAM 1 to be
within the 512MB window of KSEG. I'm unclear whether the CPU_remap
addresses count as PHSYICAL or VIRTUAL addresses.
I'm guessing that my plan won't work since I tried it and it didn't
work. My results were that the kernel booted but didn't report any
additional memory available via the 'free' command.
