Subject: [PATCH v2 00/12] crypto: caam - xts(aes) updates

From: Andrei Botila <andrei.botila@....com>

This patch series fixes some problems in CAAM's implementation of xts(aes):
 - CAAM until Era 9 can't process XTS with 16B IV
 - CAAM can only process in hardware XTS key lengths of 16B and 32B
 - These hardware limitations are resolved through a fallback
 - CAAM used to return 0 for XTS block length equal to zero

This patch series also adds a new feature in CAAM's xts(aes):
 - CAAM is now able to process XTS with 16B IV in HW

Changes since v1:
- use only get_unaligned() for calculating XTS IV size
- fixed the double calling of crypto_skcipher_set_reqsize() in case of XTS
- added a patch which modifies the return value for XTS when block length
  is equal to zero

Andrei Botila (12):
  crypto: caam/jr - add fallback for XTS with more than 8B IV
  crypto: caam/qi - add fallback for XTS with more than 8B IV
  crypto: caam/qi2 - add fallback for XTS with more than 8B IV
  crypto: caam/jr - add support for more XTS key lengths
  crypto: caam/qi - add support for more XTS key lengths
  crypto: caam/qi2 - add support for more XTS key lengths
  crypto: caam/jr - add xts check for block length equal to zero
  crypto: caam/qi - add xts check for block length equal to zero
  crypto: caam/qi2 - add xts check for block length equal to zero
  crypto: caam/jr - add support for XTS with 16B IV
  crypto: caam/qi - add support for XTS with 16B IV
  crypto: caam/qi2 - add support for XTS with 16B IV
