The register setup for the RAM we use on our iMX6D board exceeded the
maximum 121 entries. It is a 2GByte lpddr2, arranged to use both MMDC
channels on the processor. I blindly used the register sequence
generated by the tool "i.Mx6DQSDL LPDDR2 Script Aid" provided by
freescale.

Maybe the strategy for my board is to setup one channel only in DCD,
then the rest in uboot?  But, I wonder if this strategy would work for
the iMX6D "4KB-interleave" ddr memory mapping mode we intend to use?
Currently we use the "fixed"/flat memory mapping...
