dc4b0b38d4 Fix printf errors.
The compiler will help find mismatches between printf formats and
arguments if you let it.  This patch adds the necessary attributes to
declarations in include/common.h, then begins to correct the resulting
compiler warnings.  Some of these were bugs, e.g., "$d" instead of
"%d" and incorrect arguments.  Others were just annoying, like
int-long mismatches on a system where both are 32 bits.  It's worth
fixing the annoying errors to catch the real ones.

dd35479a50 Add mechanisms for CPU and board-specific Ethernet initialization
This patch is the first step in cleaning up net/eth.c, by moving Ethernet
initialization to CPU or board-specific code.  Initial implementation is
only on the Freescale TSEC controller, but others will be added soon.

f060054dad FSL LAW: Keep track of LAW allocations
Make it so we keep track of which LAWs have allocated and provide
a function (set_next_law) which can allocate a LAW for us if one is
free.

In the future we will move to doing more "dynamic" LAW allocation
since the majority of users dont really care about what LAW number
they are at.

Also, add CONFIG_MPC8540 or CONFIG_MPC8560 to those boards which needed them

4dbdb7681e 85xx: expose cpu identification
The current cpu identification code is used just to return the name
of the processor at boot.  There are some other locations that the name
is useful (device tree setup).  Expose the functionality to other bits
of code.

Also, drop the 'E' suffix and add it on by looking at the SVR version
when we print this out.  This is mainly to allow the most flexible use
of the name.  The device tree code tends to not care about the 'E' suffix.

cf6cc01427 85xx: Additional fixes and cleanup of MP code
* adjust __spin_table alignment to match ePAPR v0.94 spec
* loop over all cpus when determing who is up.  This fixes an issue if
  the "boot cpu" isn't core0.  The "boot cpu" will already be in the
  cpu_up_mask so there is no harm
* Added some protection in the code to ensure proper behavior.  These
  changes are explicitly needed but don't hurt:
  - Added eieio to ensure the "hot word" of the table is written after
    all other table updates have occurred.
  - Added isync to ensure we don't prefetch loading of table entries
    until we a released

These issues we raised by Dave Liu.

1ced121600 Update SVR numbers to expand support
FSL has taken to using SVR[16:23] as an SOC sub-version field.  This
is used to distinguish certain variants within an SOC family.  To
account for this, we add the SVR_SOC_VER() macro, and update the SVR_*
constants to reflect the larger value.  We also add SVR numbers for all
of the current variants.  Finally, to make things neater, rather than
use an enormous switch statement to print out the CPU type, we create
and array of SVR/name pairs (using a macro), and print out the CPU name
that matches the SVR SOC version.

21fae8b2b4 Invalidate INIT_RAM TLB mappings
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.

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

list of simple load/store instructions upon function entry and exit,

8716318057 85xx: Reworked initial processor init
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.
