384ce43388 crypto: inside-secure - silently return -EINVAL for input error cases
Driver was printing an error message for certain input error cases that
should just return -EINVAL, which caused the related testmgr extra tests
to flood the kernel message log. Ensured those cases remain silent while
making some other device-specific errors a bit more verbose.

36160aadb1 crypto: inside-secure - keep ivsize for DES ECB modes at 0
The driver incorrectly advertised the IV size for DES and 3DES ECB
mode as being the DES blocksize of 8. This is incorrect as ECB mode
does not need any IV.

8933259042 crypto: inside-secure - do not rely on the hardware last bit for result descriptors
When performing a transformation the hardware is given result
descriptors to save the result data. Those result descriptors are
batched using a 'first' and a 'last' bit. There are cases were more
descriptors than needed are given to the engine, leading to the engine
only using some of them, and not setting the last bit on the last
descriptor we gave. This causes issues were the driver and the hardware
aren't in sync anymore about the number of result descriptors given (as
the driver do not give a pool of descriptor to use for any
transformation, but a pool of descriptors to use *per* transformation).

This patch fixes it by attaching the number of given result descriptors
to the requests, and by using this number instead of the 'last' bit
found on the descriptors to process them.

231baecdef crypto: clarify name of WEAK_KEY request flag
CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it
sounds like it is requesting a weak key.  Actually, it is requesting
that weak keys be forbidden (for algorithms that have the notion of
"weak keys"; currently only DES and XTS do).

Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which
it can be easily confused.  (This in fact happened in the UX500 driver,
though just in some debugging messages.)

Therefore, make the intent clear by renaming it to
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS.

9744fec95f crypto: inside-secure - remove request list to improve performance
This patch main goal is to improve driver performance by moving the
crypto request from a list to a RDR ring shadow.

This is possible since there is one producer and one consume for this
RDR request shadow and one ring descriptor is left unused.
Doing this change eliminates the use of spinlock when accessing the
descriptor ring and the need to dynamicaly allocate memory per crypto
request.

The crypto request is placed in the first RDR shadow descriptor only
if there are enough descriptors, when the result handler is invoked,
it fetches the first result descriptor from RDR shadow.

25bc955103 crypto: inside-secure - improve the counter computation
A counter is given to the engine when finishing hash computation. It
currently uses the blocksize while it counts the number of 64 bytes
blocks given to the engine. This works well for all algorithms so far,
as SHA1, SHA224 and SHA256 all have a blocksize of 64 bytes, but others
algorithms such as SHA512 wouldn't work.

cda3e73a54 crypto: inside-secure - use the error handler for invalidation requests
This patch reworks the way invalidation request handlers handle the
result descriptor errors, to use the common error handling function.
This improves the drivers in terms of readability and maintainability.
