York Sun 1d71efbb03 driver/ddr: Restruct driver to allow standalone memory space 
U-boot has been initializing DDR for the main memory. The presumption
is the memory stays as a big continuous block, either linear or
interleaved. This change is to support putting some DDR controllers
to separated space without counting into main memory. The standalone
memory controller could use different number of DIMM slots.

York Sun 4e5b1bd0df driver/ddr: Change Freescale ARM DDR driver to support both big and little endian 
Initially it was believed the DDR controller on Freescale ARM would have
big endian. But some platform will have little endian.

York Sun 5614e71b49 Driver/DDR: Moving Freescale DDR driver to a common driver 
Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs.
The similar DDR controllers will be used for ARM-based SoCs.
