6904e37746 imx: mx6q DDR3 init: Fix tMRD 
MMDC1_MDCFG1.tMRD should be set to max(tMRD, tMOD) for DDR3.

For all DDR3 speed bins:
  tMRD(min) = 4 nCK
  tMOD(min) = max(12 nCK, 15 ns)

Hence, MMDC1_MDCFG1.tMRD should be set to max(12 nCK, 15 ns), which is 12 nCK
at 532 MHz, encoded as 0xB in the bit-field MMDC1_MDCFG1[8:5].

71a988aa63 imximage.cfg: run files through C preprocessor 
The '#' used as comments in the files cause the preprocessor
trouble, so change to /* */.

The mkimage command which uses this preprocessor output
was moved to arch/arm/imx-common/Makefile

.gitignore was updated to ignore .cfgtmp files.
