commit 00904aa0cd59a36d659ec93d272309e2174bcb5b upstream.
We were copying our last cipher block into the request for use as IV for
all modes of operations. Fix this by discerning the behaviour based on
the mode of operation used: copy ciphertext for CBC, update counter for
CTR.

commit 26497e72a1aba4d27c50c4cbf0182db94e58a590 upstream.
finup() operation was incorrect, padding was missing.
Fix by setting the ccree HW to enable padding.

crypto: ccree - correct host regs offset2018-06-16T07:18:22+00:00Gilad Ben-Yossefgilad@benyossef.com2018-05-24T14:19:06+00:00urn:sha1:3f0a1a04339bdd3ede1c5b787d7da7ea1e853f4a
commit 281a58c8326ca62ca6341f9d2cc2eb08044670e8 upstream.
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.
