Hi Herbert,
I'm trying to find a method to pass IVs of various lengths to an
algorithm. A particular case would be aes-gcm IV. It can have any number
of bits between 1 and 2^64.
A possible way to do this is to set the ivlen per request. Are there any
(better) ways to do this?
Thanks,
ta

The existing mv_cesa driver supports some features of the CESA IP but is
quite limited, and reworking it to support new features (like involving the
TDMA engine to offload the CPU) is almost impossible.
This driver has been rewritten from scratch to take those new features into
account.

The mv_cesa driver currently expects the SRAM memory region to be passed
as a platform device resource.
This approach implies two drawbacks:
- the DT representation is wrong
- the only one that can access the SRAM is the crypto engine
The last point is particularly annoying in some cases: for exa
We are about to add a new driver to support new features like using the
TDMA engine to offload the CPU.
Orion, Dove and Kirkwood platforms are already using the mv_cesa driver,
but Orion SoCs do not embed the TDMA engine, which means we will have to
differentiate them if we want to get TDMA support

The nx driver reads two crucial paramters from the firmware for
each crypto algorithm, the maximum SG list length and byte limit.
Unfortunately those two parameters may be bogus, or worse they
may be absent altogether. When this happens the algorithms will
still register successfully but will fail

This doesn't compile because it hasn't made it into mainline yet.
I'm afraid this patch-set will have to wait until that happens.
