MLK-10568 imx: mx7d arm2: Update LPDDR3 script to 7D_lpddr3_0_1.ds5
[The compass link for this script]
http://compass.freescale.net/livelink/livelinkfunc=ll&objid=233861153
&objAction=browse&sort=name
[Changes in the script]
1. Change the DDR freq to 528Mhz.
2. Disable ddr phy dll, just force a dll output. IC suspects the dll
in ddr phy may unlock sometimes. The side-effect is we will lost the
ability to compensate the voltage/temperature change, so it may easy
to fail at H/L temperature.
[DDR stress test result]
3 boards involved the two days stress test by using memtester tool.
One board met a kernel oops after one day test. Other two pass the
two days test.
Compared to previous DDR script, the result is much positive.
