58e5e9aff1 FSL DDR: Rewrite the FSL mpc8xxx DDR controller setup code.
The main purpose of this rewrite it to be able to share the same
initialization code on all FSL PowerPC products that have DDR
controllers.  (83xx, 85xx, 86xx).

The code is broken up into the following steps:
	GET_SPD
	COMPUTE_DIMM_PARMS
	COMPUTE_COMMON_PARMS
	GATHER_OPTS
	ASSIGN_ADDRESSES
	COMPUTE_REGS
	PROGRAM_REGS

This allows us to share more code an easily allow for board specific code
overrides.

Additionally this code base adds support for >4G of DDR and provides a
foundation for supporting interleaving on processors with more than one
controller.

ec2b74ffd3 85xx: Added support for multicore boot mechanism
Added the cpu command that provides a generic mechanism to get status,
reset, and release secondary cores in multicore processors.

Added support for using the ePAPR defined spin-table mechanism on 85xx.

2047672684 Converted all 85xx boards to use a common FSL I2C driver.
Introduced COFIG_FSL_I2C to select the common FSL I2C driver.
And removed hard i2c path from a few u-boot.lds scipts too.
Minor whitespace cleanups along the way.

f93286397e Add support for a saving build objects in a separate directory.
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.

Move the TSEC driver out of cpu/mpc85xx as it will be shared
  by the upcoming mpc83xx family as well.
