This series of patches provide AES-ECB and AES-CBC support
for the SAHARA2 cryptographic accelerator which is inside the i.MX27 SoC.
It is expected that more algorithms will be supported in the future.
For testing, a Visstrim M10 board has been used and the code related
to this platform has been
SAHARA2 HW module is included in the i.MX27 SoC from
Freescale. It is capable of performing cipher algorithms
such as AES, 3DES..., hashing and RNG too.
This driver provides support for AES-CBC and AES-ECB
by now.

Apologies if this is misthreaded, I had to hand-craft the headers.
The patch offers an entropy generator based on CPU timing jitter. The
entropy collector has the following properties:
* it does not maintain any state and therefore does not need any seed
What is this pool if it's not

We know about the existence of DT and the constant migration process
that is taking place towards it.
Moreover we are strongly interested in converting the Visstrim SM10
platform to DT. Unfortunately, there are several issues that need to

Neither i.MX25, i.MX31 nor i.MX21 have this unit. I haven't checked the
others, but I assume this is i.MX27 only.
There is Sahara variants on mx51/mx53.

Herbert,
The following patch update the stale link to the CRC32C white paper
that was referenced.
