Kevin Hao - Sept. 24, 2013, 3:03 a.m.
In the current kernel, the board files for p2041rdb, p3041ds, p4080ds,
p5020ds, p5040ds, t4240qds and b4qds are almost the same except the
machine name. So this introduces a cornet_generic machine to support
all these boards to avoid the code duplication.

With these changes the file corenet_ds.h becomes useless. Just delete
it.

v3:
  - Change the machine name from "CORENET Generic" to "CoreNet Generic".

v2:
  - Fix the typo in subject.
  - Fold the original patch 2 into this one.
  - Change the machine name from "CORENET GENERIC" to "CORENET Generic".

v1:
  - This patch is based on http://patchwork.ozlabs.org/patch/274390/
