* crypto: caam - Sweep the remnantsMarek Vasut2014-05-081-21/+20
| | | | | | | | | | | | Clean up the remnants from the rework. Constify function arguments. Note that checkpatch again complains about this space before newline, but this is the original code behavior, so I'm keeping it.

* crypto: caam - Kill the easy targetsMarek Vasut2014-05-081-12/+17
| | | | | | | | | | | | | | | Fix the functions which can be obviously done right with a simple dev_err() now. While at it, further press the on-stack allocation of buffer for sprintf() voodoo down into the abominated functions. This patch cleans up most of the functions and leaves just two remaining functions, report_ccb_status() and report_deco_status() ugly and unhappy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimize the hashing operation in the MXS-DCP by doing two adjustments: 1) Given that the output buffer for the hash is now always correctly aligned, we can just use the buffer for the DCP DMA to store the resulting hash. We thus get rid of one copying of data. Moreover, we remove an entry from dcp_coherent_block{} and thus lower the memory footprint of the driver. 2) We map the output buffer for the hash for DMA only in case we will output the hash, not always, as it was now.

| * crypto: ccp - Prevent a possible lost CCP command requestTom Lendacky2014-02-271-0/+4
| | | | | | | | | | | | | | | | | | | | If a CCP command has been queued for processing at the crypto layer then, when dequeueing it for processing, the "can backlog" flag must be set so that the request isn't lost if the CCP backlog queue limit is reached.

| * crypto: caam - writel() arguments are swappedDan Carpenter2014-02-271-2/+2
| | | | | | | | | | | | | | | | | | | | My guess is that this little endian configuration is never found in real life, but if it were then the writel() arguments are in the wrong order so the driver would crash immediately.

| * crypto: tegra - remove driverStephen Warren2014-02-274-1202/+0
| | | | | | | | | | | | | | | | | | | | | | This driver has never been hooked up in any board file, and cannot be instantiated via device tree. I've been told that, at least on Tegra20, the HW is slower at crypto than the main CPU. I have no test-case for it. Hence, remove it.
