3924384060 mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache
This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.

lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

2d0daa0361 POWERPC 86xx: Move BAT setup code to C
This is needed because we will be possibly be locating
devices at physical addresses above 32bits, and the asm
preprocessing does not appear to deal with ULL constants
properly. We now call write_bat in lib_ppc/bat_rw.c.

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

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.
