* crypto: caam - Fix the 'quoted string split across lines'Marek Vasut2014-05-081-59/+18
| | | | | | | | | | | | Fix the checkpatch warnings that the strings were split across multiple lines. Checkpatch now complains about lines over 80, but this is better, since we can actually grep the source code for these strings now.

* 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.

| | | | | | | | | | This macro is just like an encyclopedia of string handling done wrong. This must die. This is so wrong on so many levels.

* crypto: caam - Clean up report_deco_status()Marek Vasut2014-05-081-18/+13
| | | | | | | | | | | Clean this function up and rework it into sensible shape. This function now contains one single dev_err() instead of the previous insanity full of memory allocation, chaotic string handling and use of SPRINTFCAT().

* 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.

* crypto: caam - Pass error type into the functionsMarek Vasut2014-05-081-10/+21
| | | | | | | | | | | | | | Pass the error type string into the functions, so they can handle the printing of the string. This is now still using the very unsafe sprintf(), but we will fix that. While at this, pass the device pointer too, so we can dev_err() functions readily when we start fixing this proper.

* crypto: caam - Implement fast-path for error codes with no handlerMarek Vasut2014-05-081-2/+10
| | | | | | | | | | | | | | | Implement fast-path error code printout for errors with no associated handler function. This reduces calls to this kmalloc() nonsense in SPRINTFCAT() already. Note that the format of output is compatible with the old code, even if -- exposed like this -- it looks a bit weird. Checkpatch complains on this one as well.

* crypto: caam - Pull all the error codes outMarek Vasut2014-05-081-143/+147
| | | | | | | | | | | | | | | Pull the error code <-> error string mapping tables out of the function so the code becomes readable. This lets me see the real flesh of the functions, without all that flab clouding the view. Note: There is a checkpatch issue with quoted strings across multiple lines. I will fix that in a subsequent patch to keep the changes small and separate.

| | | | | | | | | | | | | The SEC v4.x' RNGB h/w block self-initialized. RNG4, available on SEC versions 5 and beyond, is based on a different standard that requires manual initialization. Also update any new errors From the SEC v5.2 reference manual: The SEC v5.2's RNG4 unit reuses some error IDs, thus the addition of rng_err_id_list over the CHA-independent err_id_list.

* crypto: caam - ARRAY_SIZE() vs sizeof()Dan Carpenter2011-03-271-4/+4
| | | | | | | | | | 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 Phillips2011-03-271-0/+248
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.
