      crypto: caam - desc.h fixes · 2090456a
      Horia Geantă authored 
      1. fix HDR_START_IDX_MASK, HDR_SD_SHARE_MASK, HDR_JD_SHARE_MASK
Define HDR_START_IDX_MASK consistently with the other masks:
mask = bitmask << offset

2. OP_ALG_TYPE_CLASS1 and OP_ALG_TYPE_CLASS2 must be shifted.

3. fix FIFO_STORE output data type value for AFHA S-Box

4. fix OPERATION pkha modular arithmetic source mask

5. rename LDST_SRCDST_WORD_CLASS1_ICV_SZ to
LDST_SRCDST_WORD_CLASS1_IV_SZ (it refers to IV, not ICV).

      Horia Geantă authored 
      Commit 4464a7d4
("crypto: caam - remove error propagation handling")
removed error propagation handling only from caamalg.

Do this in all other places: caamhash, caamrng.
Update descriptors' lengths appropriately.

      crypto: caam - fix AEAD givenc descriptors · d128af17
      Alex Porosanu authored 
      The AEAD givenc descriptor relies on moving the IV through the
output FIFO and then back to the CTX2 for authentication. The
SEQ FIFO STORE could be scheduled before the data can be
read from OFIFO, especially since the SEQ FIFO LOAD needs
to wait for the SEQ FIFO LOAD SKIP to finish first. The
SKIP takes more time when the input is SG than when it's
a contiguous buffer. If the SEQ FIFO LOAD is not scheduled
before the STORE, the DECO will hang waiting for data
to be available in the OFIFO so it can be transferred to C2.
In order to overcome this, first force transfer of IV to C2
by starting the "cryptlen" transfer first and then starting to
store data from OFIFO to the output buffer.

      Alex Cope authored 
      This code is unlikely to be useful in the future because transforms
don't know how often keys will be changed, new algorithms are unlikely
to use lle representation, and tables should be replaced with
carryless multiplication instructions when available.

      Crypto: mv_cesa - Switch to using managed resources · 650d4a97
      Nadim almas authored 
      Switch to resource-managed function devm_kzalloc instead
of kzalloc and remove unneeded kfree

Also, remove kfree in probe function and remove

      crypto: ccp - Fix handling of RSA exponent on a v5 device · e6414b13
      Gary R Hook authored 
      The exponent size in the ccp_op structure is in bits. A v5
CCP requires the exponent size to be in bytes, so convert
the size from bits to bytes when populating the descriptor.

The current code references the exponent in memory, but
these fields have not been set since the exponent is
actually store in the LSB. Populate the descriptor with
the LSB location (address).
