This patch is only compile-tested for PowerPC and tested on ARM.
According to the datasheets for i.MX6 and P1010 this should be correct, though.

I however don't know what combinations actually *have* to be caught, as I don't

Hi all!
I have a question regarding the use of the backlog in a driver
using the crypto API.
In my driver ("crypto: sahara - SHA support") I had a problem with
using the backlog when I am using more than one thread to enqueue
the requests and have a queue depth of 1. What happens is, that I
run in

Hi!
This series adds support for the SAHARA crypto module on i.MX53 in 1/2
and than adds support for SHA1/256 in 2/2.
Changes since last version:
- save the hash state in the sahara request struct
- fixed the hash remainder calculation
