9c5e60f656 rPi MMU: Fixes to hrev44189
* I had the wrong addresses, 0x20 was the physical
  address not a mapped one.
* Attempt to map uart in mmu post mmu_init.

b8733e36c7 rPi MMU: Working towards mapped memory
* BCM2708 defines no longer assume 0x20 address
  We will be throwing away the blob memory mapping
  and using our own.
* Use existing blob mapping to turn GPIO led on pre mmu_init
* Remap MMU hardware addresses from 0x7E. We could map each device,
  however the kernel will throw away the mappings again anyway. For
  now we just map the whole range and use offsets.
* Serial uart no longer works, however at least
  we know why now :). Serial driver now needs to
  use mapped address.

77591e9657 rPi: MMU Work
* Use U-Boot mmu code as base
* This will be factored out someday into common arch mmu
  code when we can read Flattened Device Trees
* Move mmu_init after serial_init.
  Temporary change as we will want serial_init to use
  memory mapped addresses... for debugging.
