Commit 0db37dc... (and some others) changed the INIT_RAM TLB
mappings to be unguarded. This collided with an existing "bug"
where the mappings for the INIT_RAM were being kept around.
This meant that speculative loads to those addresses were
succeeding in the TLB, and going out to the bus, where they
were causing an exception (there's nothing at that address). The
Flash code was coincidentally causing such a speculative load.
Rather than go back to mapping the INIT RAM as guarded, we fix
it so that the entries for the INIT_RAM are invalidated. Thus
the speculative loads will fail in the TLB, and have no effect.

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.

Reworked the initial processor initialzation sequence:
* introduced cpu_early_init_f that is run in address space 1 (AS=1)
* Moved TLB/LAW and CCSR init into cpu_early_init_f()
* Reworked initial asm code to do most of the core init before TLBs
The main reasons for these changes are to allow handling of 36-bit phys
addresses in the future and some of the issues that will exist when we
do that.
There are a few caveats on what can be initialized via the LAW and TLB
static tables:
* TLB entry 14/15 can't be initialized via the TLB table
* any LAW that covers the implicit boot window (4G-8M to 4G) must map to
the code that is currently executing.

Add a set of functions to manipulate TLB entries:

The current implementation does not set the number of bank address bits
(BA) in the processor. The default assumes 2 logical bank bits. This
works fine for a DIMM that uses devices with 4 internal banks (SPD
byte17 = 0x4) but needs to be set appropriately for a DIMM that uses
devices with 8 internal banks (SPD byte17 = 0x8).

Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.

work at 33MHz
