ENGR00136170 MX50 Add ZQ calibration revision for TO1.1
All type of DDRs will be affected.
ddr script is available here:
http://compass.freescale.net/livelink/livelink/open/218722501
Two key points:
1. LPDDR2 ZQ calibration is different from mDDR/DDR2,
fixed in this version(they're same before).
2. TO1.1 ZQ calibration is _NOT_ compatible with TO1.0.
U-Boot default config is for TO1.1.
Please switch off CONFIG_ZQ_CALIB option if compile for TO1.0.
Other fixes:
1. Change drive strength to 0x00200000 for all ddr types.
2. Add missed config for IOMUXC_SW_PAD_CTL_PAD_DRAM_OPEN and
IOMUXC_SW_PAD_CTL_PAD_DRAM_OPENFB.
