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.

4933b91f8a 86xx: Support new law setup method and convert mpc8641
Adds the support code in cpu/mpc86xx for the new law setup code
recently created fsl_law.c, and changes the MPC8641HPCN config
to use this code.

1a41f7ce9c 86xx: Rearrange the sequence in start.S
* split the BAT initialization so that only 2 BATs (for the boot page
and stack) are programmed very early on.  The rest are initialized later.
* Move other BAT setup,  ccsrbar setup, and law setup later in the code
after translation has been enabled.

These changes will facilitate the moving of law and BAT initialization
to C code, and will aid with 36-bit physical addressing support.
