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.

71074abbe0 8xxx-fdt: set ns16550 clock from CFG_NS16550_CLK, not bi_busfreq
Some boards that have external 16550 UARTs don't have a direct
tie between bi_busfreq and the clock used for the UARTs.  Boards
that do have such a tie should set CFG_NS16550_CLK to be
get_bus_freq(0) -- which most of them do already.

3473ab7372 Feed the watchdog in u-boot for 8610 board.
The watchdog on 8610 board is enabled by setting sw[6]
to on. Once enabled, the watchdog can not be disabled
by software. So feed the dog in u-boot is necessary for
normal operation.

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.

279726bd00 MPC86xx: Change traps.c to not reference non-addressable memory
Currently, END_OF_RAM is used by the trap code to determine if
we should attempt to access the stack pointer or not. However,
on systems with a lot of RAM, only a subset of the RAM is
guaranteed to be mapped in and accessible.  Change END_OF_RAM
to use get_effective_memsize() instead of using the raw ram
size out of the bd to prevent us from trying to access
non-mapped memory.

f5a2425919 7450 and 86xx L2 cache invalidate bug corrections
The 7610 and related parts have an L2IP bit in the L2CR that is
monitored to signal when the L2 cache invalidate is complete whereas the
7450 and related parts utilize L2I for this purpose. However, the
current code does not account for this difference. Additionally the 86xx
L2 cache invalidate code used an "andi" instruction where an "andis"
instruction should have been used.

This patch addresses both of these bugs.

1b9ed2574a Fix calculation of I2C clock for some 86xx chips
Some 86xx chips use CCB as the base clock for the I2C, and others used CCB/2.
There is no pattern that can be used to determine which chips use which
frequency, so the only way to determine is to look up the actual SOC
designation and use the right value for that SOC.

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.

13f5433f70 86xx: Convert sbc8641d to use libfdt.
This is the proper fix for a missing closing brace in the function
ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com.
The ft_cpu_setup() function in mpc8641hpcn.c should have been
removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE,
but was missed.  Only, the sbc8641d was nominally still using it.
It all got ripped out, and the funcality that was in ft_board_setup()
was refactored to remove the CPU portions into the new file
cpu/mpc86xx/fdt.c instead.  Make sbc8641d use this now.

Based loosely on an original patch from joe.hamman@embeddedspecialties.com

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.

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.
