Peng,

I have found one more piece that is missing from the lpddr4
initialization.  We don't have a structure, or place to change the DDR
PHY DQ lane to memory mapping registers.  Our board requires this and
was failing until I patched it in.

According to the code generated from DDR tool this should happen after
/* step7 [0]--1: disable quasi-dynamic programming */
