> Running a memtest in U-Boot and Linux shows that some Colibri iMX6
> produce bitflips at temperatures above 60°C. This happens because the
> RALAT and WALAT values on the Colibri iMX6 are too low. The problems
> were introduced by commit 09dbac8174c4 ("mx6: ddr: Restore ralat/walat
> in write level calibration") before the calibration process overwrote
> the values and set them to the maximum value. With this commit, we make
> sure that the RALAT and WALAT values are set to the maximum values
> again. This has been proven to work for years.
