/*
* caam - Freescale FSL CAAM support for crypto API
*
* Copyright 2008-2011 Freescale Semiconductor, Inc.

*
* Based on talitos crypto API driver.
*
* relationship of job descriptors to shared descriptors (SteveC Dec 10 2008):
*
* --------------- ---------------
* | JobDesc #1 |-------------------->| ShareDesc |
* | *(packet 1) | | (PDB) |
* --------------- |------------->| (hashKey) |
* . | | (cipherKey) |
* . | |-------->| (operation) |
* --------------- | | ---------------
* | JobDesc #2 |------| |
* | *(packet 2) | |
* --------------- |
* . |
* . |
* --------------- |
* | JobDesc #3 |------------
* | *(packet 3) |
* ---------------
*
* The SharedDesc never changes for a connection unless rekeyed, but
* each packet will likely be in a different place. So all we need
* to know to process the packet is where the input is, where the
* output goes, and what context we want to process with. Context is
* in the SharedDesc, packet references in the JobDesc.
*
* So, a job desc looks like:
*
* ---------------------
* | Header |
* | ShareDesc Pointer |
* | SEQ_OUT_PTR |
* | (output buffer) |
* | (output length) |
* | SEQ_IN_PTR |
* | (input buffer) |
* | (input length) |
* ---------------------
