Internal memory controller counters can reach a bad state after
training in DDR4 mode if accumulated ECC or DBI mode is eanbled.

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.

Initially it was believed the DDR controller on Freescale ARM would have
big endian. But some platform will have little endian.

Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs.
The similar DDR controllers will be used for ARM-based SoCs.
