* crypto: ccree - correct host regs offsetGilad Ben-Yossef2018-05-311-2/+4
| | | | | | | | | | | | | The product signature and HW revision register have different offset on the older HW revisions. This fixes the problem of the driver failing sanity check on silicon despite working on the FPGA emulation systems.

* crypto: ccree - introduce CryptoCell driverGilad Ben-Yossef2018-02-151-0/+142
Introduce basic low level Arm TrustZone CryptoCell HW support. This first patch doesn't actually register any Crypto API transformations, these will follow up in the next patch. This first revision supports the CC 712 REE component. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
