crypto: caam - Add support for the Freescale SEC4/CAAM 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.

crypto: caam - fix printk recursion for long error texts during recent descriptor development, an Invalid Sequence Command error triggered a: BUG: recent printk recursion! due to insufficient memory allocated for the error text. The Invalid Sequence Command error text is the longest. The length of the maximum error string is computed as the sum of: "DECO: ": 6 "jump tgt desc idx 255: ": 23 Invalid Sequence Command text: 272 zero termination character: 1 i.e, 302 characters. Define this maximum error string length in error.h and fix caam_jr_strstatus callsites.

crypto: caam - Contain caam_jr_strstatus() ugliness The tentacles of this function were firmly attached to various places in the CAAM code. Just cut them, or this cthulhu function will sprout them anew.
