The CAAM in IMX parts doesn't support public key hardware acceleration (PKHA), so don't use RSA_FREESCALE_EXP. If you try to use it on IMX (assuming you have the clocks enabled first) you will get back an "Invalid KEY Command" error since PKHA isn't a valid key destination for these parts.

The Modular Exponentiation algorithm in RSA is implemented using
|
|
driver model. So CONFIG_DM needs to be enabled by default for this
|
|
library to function.
|

The signing part is build into mkimage regardless of this
|
|
option. The software based modular exponentiation is built into
|
|
mkimage irrespective of this option.
