2019-04-25crypto: ccree - read next IV from HWGilad Ben-Yossef
We were computing the next IV in software instead of reading it from HW on the premise that this can be quicker due to the small size of IVs but this proved to be much more hassle and bug ridden than expected. Move to reading the next IV as computed by the HW. This fixes a number of issue with next IV being wrong for OFB, CTS-CBC and probably most of the other ciphers as well.

IV generation is not available via the skcipher interface. Remove the left over support of it from the ablkcipher days. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2018-05-05crypto: ccree - enable support for hardware keysGilad Ben-Yossef
Enable CryptoCell support for hardware keys. Hardware keys are regular AES keys loaded into CryptoCell internal memory via firmware, often from secure boot ROM or hardware fuses at boot time. As such, they can be used for enc/dec purposes like any other key but cannot (read: extremely hard to) be extracted since since they are not available anywhere in RAM during runtime. The mechanism has some similarities to s390 secure keys although the keys are not wrapped or sealed, but simply loaded offline. The interface was therefore modeled based on the s390 secure keys support. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
