That is not work.
The patch not for linux-2.6.35 or linux-2.6.38.
On my test team, u-boot mode we can read or write the sata data, but linux kernel mode we could do it only  raised the CPU temperature to 45 degrees Celsius.
Now we have 30% chips have this phenomenon.
 this issue was random happened, anyone else have imx535 have loco board? Who could give us some help
