ICV check failures are part of normal operation;
leave user notification up to the higher levels,
as is done in s/w algorithm implementations.

The error code returned by hardware is four bits wide with an expected
zero MSB. A hardware error condition where the error code can get between
0x8 and 0xf will trigger an out of bound array access on the error
message table.
This patch fixes the invalid array access following such an error and
reports the condition.

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.

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.

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().

Just dissolve this function so it's not in the way of applying
further white magic cleanup down the line.

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.

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.

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.

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 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.

checkstack reports report_deco_status(), report_ccb_status() as
particularly excessive stack users. Move their lookup tables
off the stack and put them in .rodata.

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.

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.

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.
