crypto: inside-secure - remove request list to improve performance

2018-07-08T16:30:19+00:00

This patch main goal is to improve driver performance by moving the
crypto request from a list to a RDR ring shadow.

This is possible since there is one producer and one consume for this
RDR request shadow and one ring descriptor is left unused.
Doing this change eliminates the use of spinlock when accessing the
descriptor ring and the need to dynamicaly allocate memory per crypto
request.

The crypto request is placed in the first RDR shadow descriptor only
if there are enough descriptors, when the result handler is invoked,
it fetches the first result descriptor from RDR shadow.

crypto: inside-secure - set tx_max_cmd_queue to 32

2018-07-08T16:30:15+00:00

The ORO bridge (connected to the EIP197 write channel) does not
generate back pressure towards the EIP197 when its internal FIFO is
full. It assumes that the EIP will not drive more write transactions
than the maximal supported outstanding (32).

Hence tx_max_cmd_queue must be configured to 5 (or less).

crypto: inside-secure - adjust the TRC configuration for EIP197D

2018-07-08T16:30:14+00:00

This patch updates the TRC configuration so that the version of the
EIP197 engine being used is taken into account, as the configuration
differs between the EIP197B and the EIP197D.

crypto: inside-secure - eip197d support

2018-07-08T16:30:13+00:00

This patch adds support for the eip197d engine to the Inside Secure
SafeXcel cryptographic driver. This new engine is similar to the eip197b
and reuse most of its code.

crypto: inside-secure - add multiple processing engine support

2018-07-08T16:30:13+00:00

So far a single processing engine (PE) was configured and used in the
Inside Secure SafeXcel cryptographic engine driver. Some versions have
more than a single PE. This patch rework the driver's initialization to
take this into account and to allow configuring more than one PE.
