2 * caam - Freescale FSL CAAM support for crypto API
3 *
4 * Copyright 2008-2011 Freescale Semiconductor, Inc.

6 * Based on talitos crypto API driver.
7 *
8 * relationship of job descriptors to shared descriptors (SteveC Dec 10 2008):
9 *
10 * --------------- ---------------
11 * | JobDesc #1 |-------------------->| ShareDesc |
12 * | *(packet 1) | | (PDB) |
13 * --------------- |------------->| (hashKey) |
14 * . | | (cipherKey) |
15 * . | |-------->| (operation) |
16 * --------------- | | ---------------
17 * | JobDesc #2 |------| |
18 * | *(packet 2) | |
19 * --------------- |
20 * . |
21 * . |
22 * --------------- |
23 * | JobDesc #3 |------------
24 * | *(packet 3) |
25 * ---------------
26 *
27 * The SharedDesc never changes for a connection unless rekeyed, but
28 * each packet will likely be in a different place. So all we need
29 * to know to process the packet is where the input is, where the
30 * output goes, and what context we want to process with. Context is
31 * in the SharedDesc, packet references in the JobDesc.
32 *
33 * So, a job desc looks like:
34 *
35 * ---------------------
36 * | Header |
37 * | ShareDesc Pointer |
38 * | SEQ_OUT_PTR |
39 * | (output buffer) |
40 * | (output length) |
41 * | SEQ_IN_PTR |
42 * | (input buffer) |
43 * | (input length) |
44 * ---------------------
