e7670f6c1e PPC: Use r2 instead of r29 as global data pointer 
R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.

Use r2 instead.

  use a jump table; please see doc/README.standalone for details
