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.

The qce driver use two dma_map_sg path according to SG are chained
or not.
Since dma_map_sg can handle both case, clean the code with all
references to sg chained.
Thus removing qce_mapsg, qce_unmapsg and qce_countsg functions.

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.
