Dose iMX6ULL support CAAM driver?

Dear all,
Now I try to port BSP from iMX6UL to iMX6ULL，but always occur kernel panic after load CAAM driver.

Log as follows,

Load CAAM driver failed, then I find some info in this doc. Dose it mean iMX6ULL not support CAAM feature？

Hi Shi,

The i.MX6ULL does not have CAAM, you need to remove that driver.
