[GIT PULL] Initial OLPC XO-1.75/XO-4 support

[dsd@laptop.org (Daniel Drake)]

Hi,

These patches add support for booting OLPC XO-1.75 (Marvell MMP2) and OLPC
XO-4 (Marvell MMP3) which present device trees from OpenFirmware.

With the exception of the most recent patch, which has been acked (I think),
the other patches were posted about 2 weeks ago and haven't received
any comments from the MMP arch maintainers.

Please consider for the next available merge window (not sure if we're
now too late for 3.11, no big deal if so).

The following changes since commit 8bb495e3f02401ee6f76d1b1d77f3ac9f079e376:

  Linux 3.10 (2013-06-30 15:13:29 -0700)
