"Here is the crypto update for 3.15:
- Added 3DES driver for OMAP4/AM43xx
- Added AVX2 acceleration for SHA
- Added hash-only AEAD algorithms in caam
- Removed tegra driver as it is not functioning and the hardware is
too slow
- Allow blkcipher walks over AEAD (needed for ARM)
- Fixed unprotected FPU/SSE access in ghash-clmulni-intel
- Fixed highmem crash in omap-sham
- Add (zero entropy) randomness when initialising hardware RNGs
- Fixed unaligned ahash comletion functions

Commit 61bb86bba1
("crypto: caam - set descriptor sharing type to SERIAL")
changed the descriptor sharing mode from SHARE_WAIT to SHARE_SERIAL.
All descriptor commands that handle the "ok to share" and
"error propagation" settings should also go away, since they have no
meaning for SHARE_SERIAL.

Found by the kbuild test robot, the first argument to caam_init_rng
has a spurious ampersand.

HIGHMEM pages may not be mapped so we must kmap them before accessing.
This resolves a random OOPs error that was showing up during OpenSSL SHA tests.

This patch allocates memory from DMAable region to the caam_rng_ctx object,
earlier it had been statically allocated which resulted in errorneous
behaviour on inserting the caamrng module at the runtime.

Optimize the hashing operation in the MXS-DCP by doing two adjustments:
1) Given that the output buffer for the hash is now always correctly aligned,
we can just use the buffer for the DCP DMA to store the resulting hash.
We thus get rid of one copying of data. Moreover, we remove an entry from
dcp_coherent_block{} and thus lower the memory footprint of the driver.
2) We map the output buffer for the hash for DMA only in case we will output
the hash, not always, as it was now.

1) SSYNC instruction is blackfin specific and takes no effect in this driver.
2) DMA descriptor and SG middle buffer are in DMA coherent memory. No need
to flush.
3) Turn kzalloc, ioremap and request_irq into managed device APIs respectively.

When the crypto layer is able to queue up a command for processing
by the CCP on the initial call to ccp_crypto_enqueue_request and
the CCP returns -EBUSY, then if the backlog flag is not set the
command needs to be freed and not added to the active command list.

Invoke the callback routine associated with the crypto context
if an error is encountered sending the command to the CCP during

by the command.

If a CCP command has been queued for processing at the
crypto layer then, when dequeueing it for processing, the
"can backlog" flag must be set so that the request isn't
lost if the CCP backlog queue limit is reached.

My guess is that this little endian configuration is never found in real
life, but if it were then the writel() arguments are in the wrong order
so the driver would crash immediately.

This driver has never been hooked up in any board file, and cannot be
instantiated via device tree. I've been told that, at least on Tegra20,
the HW is slower at crypto than the main CPU. I have no test-case for
it. Hence, remove it.

Add omap-des driver with platform data for OMAP4/AM43xx. Support added for DES
ECB and CBC modes. Also add support for 3DES operation where 3 64-bit keys are
used to perform a DES encrypt-decrypt-encrypt (des3_ede) operation on a buffer.
Tests have been conducted with the CRYPTO test manager, and functionality is
verified at different page length alignments.
