crypto: qce - Qualcomm crypto engine driver The driver is separated by functional parts. The core part implements a platform driver probe and remove callbaks. The probe enables clocks, checks crypto version, initialize and request dma channels, create done tasklet and init crypto queue and finally register the algorithms into crypto core subsystem. - DMA and SG helper functions implement dmaengine and sg-list helper functions used by other parts of the crypto driver. - ablkcipher algorithms implementation of AES, DES and 3DES crypto API callbacks, the crypto register alg function, the async request handler and its dma done callback function. - SHA and HMAC transforms implementation and registration of ahash crypto type. It includes sha1, sha256, hmac(sha1) and hmac(sha256). - infrastructure to setup the crypto hw contains functions used to setup/prepare hardware registers for all algorithms supported by the crypto block. It also exports few helper functions needed by algorithms: - to check hardware status - to start crypto hardware - to translate data stream to big endian form Adds register addresses and bit/masks used by the driver as well.

crypto: sha - split sha.h into sha1.h and sha2.h Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.
