Enables the driver module for Freescale's Cryptographic Accelerator
|
|
and Assurance Module (CAAM), also known as the SEC version 4 (SEC4).
|
|
This module creates job ring devices, and configures h/w
|
|
to operate as a DPAA component automatically, depending
|
|
on h/w feature availability.
|
|
|
|
To compile this driver as a module, choose M here: the module
|

will be called caam.
