d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

b979e35230 ARM: imx6: Adjust DDR DRAM settings on DHCOM i.MX6 PDK
The board uses T-topology for the four x16 DRAM chips, so remove
the write-leveling from the SPL as that is only usefly on fly-by
topology and can be harmful on T-topology. Also update the DRAM
timing with values from calibration on multiple boards.
