* crypto: talitos - Perform auth check in h/w if on sec 2.1 and aboveKim Phillips2008-12-251-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SEC version 2.1 and above adds the capability to do the IPSec ICV memcmp in h/w. Results of the cmp are written back in the descriptor header, along with the done status. A new callback is added that checks these ICCR bits instead of performing the memcmp on the core, and is enabled by h/w capability. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> After testing on different parts, another condition was added before using h/w auth check because different SEC revisions require different handling. The SEC 3.0 allows a more flexible link table where the auth data can span separate link table entries. The SEC 2.4/2.1 does not support this case. So a test was added in the decrypt routine for a fragmented case; the h/w auth check is disallowed for revisions not having the extent in the link table; in this case the hw auth check is done by software. A portion of a previous change for SEC 3.0 link table handling was removed since it became dead code with the hw auth check supported. This seems to be the best compromise for using hw auth check on supporting SEC revisions; it keeps the link table logic simpler for the fragmented cases.

* crypto: talitos - Implement done interrupt mitigationLee Nipper2008-12-251-1/+2
| | | | | | | | | | | | | In talitos_interrupt, upon one done interrupt, mask further done interrupts, and ack only any error interrupt. In talitos_done, unmask done interrupts after completing processing. In flush_channel, ack each done channel processed. Keep done overflow interrupts masked because even though each pkt is ack'ed, a few done overflows still occur.

* crypto: talitos - Add support for 3desLee Nipper2008-07-101-2/+1
| | | | | | | | | | This patch adds support for authenc(hmac(sha1),cbc(des3_ede)) to the talitos crypto driver for the Freescale Security Engine. Some adjustments were made to the scatterlist to link table conversion to make 3des work for ping -s 1439..1446.

* crypto: talitos - Freescale integrated security engine (SEC) driverKim Phillips2008-07-101-0/+200
Add support for the SEC available on a wide range of PowerQUICC devices, e.g. MPC8349E, MPC8548E. This initial version supports authenc(hmac(sha1),cbc(aes)) for use with IPsec. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
