The functions to save original request within a newly adjusted request and it's counterpart to restore the original request can be re-used by more code in the crypto/ahash.c file. Pull these functions out from the code so they're available. Signed-off-by: NMarek Vasut <marex@denx.de> Cc: David S.

Add documentation for the pointer voodoo that is happening in crypto/ahash.c in ahash_op_unaligned(). This code is quite confusing, so add a beefy chunk of documentation. Moreover, make sure the mangled request is completely restored after finishing this unaligned operation. This means restoring all of .result, .base.data and .base.complete . Also, remove the crypto_completion_t complete = ... line present in the ahash_op_unaligned_done() function. This type actually declares a function pointer, which is very confusing. Finally, yet very important nonetheless, make sure the req->priv is free()'d only after the original request is restored in ahash_op_unaligned_done(). The req->priv data must not be free()'d before that in ahash_op_unaligned_finish(), since we would be accessing previously free()'d data in ahash_op_unaligned_done() and cause corruption.

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.
