While working on an LX2160 based board and updating to latest mainline I noticed problems using the HW accelerated hash functions on this platform, when trying to boot a FIT Kernel image. Here the resulting error message:

CAAM was not setup properly or it is faulty error! Bad hash value for 'hash-1' hash node in 'kernel-1' image node Bad Data Hash ERROR: can't get kernel image!
Testing and checking with Gaurav Jain from NXP has revealed, that this alignment check is not necessary here at all. So let's remove this check completely.

I applied this patch against top of tree U-Boot, but I am still getting the following error on a kontron-sl-mx8mm board with the options below selected:
Thomas Schäfer sees this behavior also on an imx8mn NXP evk board. Thus I added him to this thread.
CONFIG_IMX_HAB=y CONFIG_SPL_DRIVERS_MISC=y

Not sure why dev_get_priv is returning NULL.
I am using the TF-A from NXP: BL31: v2.4(release):lf-5.15.5-1.0.0-10-gcb51a0faa4
If CONFIG_IMX_HAB=y is not selected, then sha256 is calculated by software and the fitImage boots.
Does anyone have any suggestions?
Thanks,
