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.

2491167c24 86xx: Allow for fewer DDR slots per memory controller.
As a direct correlation exists between DDR DIMM slots
and SPD EEPROM addresses used to configure them, use
the individually defined SPD_EEPROM_ADDRESS* values to
determine if a DDR DIMM slot should have its SPD
configuration read or not.

Effectively, this now allows for 1 or 2 DIMM slots
per memory controller.

63cec5814f Make MPC8641's PCI/PCI-E driver a common driver for many FSL parts.
All of the PCI/PCI-Express driver and initialization code that
was in the MPC8641HPCN port has now been moved into the common
drivers/fsl_pci_init.c.  In a subsequent patch, this will be
utilized by the 85xx ports as well.

Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added.

Also enable the second PCI-Express controller on 8641
by getting its BATS and CFG_ setup right.

Fixed a u16 vendor compiler warning in AHCI driver too.
