Enables the driver module for Freescale's Cryptographic Accelerator
|
||
|
|
and Assurance Module (CAAM), also known as the SEC version 4 (SEC4).
|
||
|
|
This module adds a job ring operation interface, 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.
