| * crypto: picoxcell - fix possible status FIFO overflowJamie Iles2011-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPAcc's have 2 equally sized FIFO's - a command FIFO and a status FIFO. The command FIFO takes the requests that are to be performed and the status FIFO reports the results. It is possible to get into the situation where there are more free spaces in the command FIFO than the status FIFO if we don't empty the status FIFO quickly enough resulting in a possible overflow of the status FIFO. This can result in incorrect status being reported in the status FIFO. Make sure that when we are submitting requests the number of requests that have been dispatched but not yet popped from the status FIFO does not exceed the size of a single FIFO.

| * crypto: padlock - Add SHA-1/256 module for VIA NanoBrilly Wu2011-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new SHA-1/256 module that never needs any fallback and just calls the PadLock hardware instruction supported from VIA Nano processors to implement the "update" and "final" function. They are respectively named "sha1_alg_nano" and "sha256_alg_nano", and will be used on any VIA Nano processor or the later ones. On VIA C7 CPU, the "sha1_alg" and "sha256_alg" modules will still be used as before.

| | | | | | | | | | | | | | | | | | | | ARRAY_SIZE() was intended here instead of sizeof(). sizeof() is four times larger than ARRAY_SIZE(). outstr is normally 256 chars so printing garbage to it could overfill the buffer and corrupt memory.

| * crypto: caam - Add support for the Freescale SEC4/CAAMKim Phillips2011-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SEC4 supercedes the SEC2.x/3.x as Freescale's Integrated Security Engine. Its programming model is incompatible with all prior versions of the SEC (talitos). The SEC4 is also known as the Cryptographic Accelerator and Assurance Module (CAAM); this driver is named caam. This initial submission does not include support for Data Path mode operation - AEAD descriptors are submitted via the job ring interface, while the Queue Interface (QI) is enabled for use by others. Only AEAD algorithms are implemented at this time, for use with IPsec. Many thanks to the Freescale STC team for their contributions to this driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | Previous commit "removed redundant locking" introduced a bug in handling backlog.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DMA is set to use burst mode also for source channel. It should descrease memory bandwidth needs. DMA synchronization is set to use prefetch mechanism. SHAM block is behind L4 bus and it doesn't have fifo. SHAM block is stalling as long as the new data is available. It takes time to fetch data from memory and transfer it via L4 bus. With prefetch enabled, data is waiting in DMA fifo and SHAM block receives new data block faster. This increases SHA processing speed up to 30 percent depending on the bus / memory load.
