crypto: sha256 - Remove sha256/224_init code duplication
lib/crypto/sha256.c and include/crypto/sha256_base.h define
99% identical functions to init a sha256_state struct for sha224 or
sha256 use.
crypto: sha256 - Remove sha256/224_init code duplication
lib/crypto/sha256.c and include/crypto/sha256_base.h define
99% identical functions to init a sha256_state struct for sha224 or
sha256 use.
This commit moves the functions from lib/crypto/sha256.c to
include/crypto/sha.h (making them static inline) and makes the
sha224/256_base_init static inline functions from
include/crypto/sha256_base.h wrappers around the now also
static inline include/crypto/sha.h functions.

crypto: sha256 - Add sha224 support to sha256 library code
Add sha224 support to the lib/crypto/sha256 library code. This will allow

crypto: sha256 - Add sha224 support to sha256 library code
Add sha224 support to the lib/crypto/sha256 library code. This will allow
us to replace both the sha256 and sha224 parts of crypto/sha256_generic.c
when we remove the code duplication in further patches in this series.

crypto: sha256 - Make lib/crypto/sha256.c suitable for generic use
Before this commit lib/crypto/sha256.c has only been used in the s390 and
x86 purgatory code, make it suitable for generic use:
* Export interesting symbols
* Add -D__DISABLE_EXPORTS to CFLAGS_sha256.o for purgatory builds to
avoid the exports for the purgatory builds
* Add to lib/crypto/Makefile and crypto/Kconfig

crypto: sha256 - Use get/put_unaligned_be32 to get input, memzero_explicit

crypto: sha256 - Use get/put_unaligned_be32 to get input, memzero_explicit
Use get/put_unaligned_be32 in lib/crypto/sha256.c to load / store data
so that it can be used with unaligned buffers too, making it more generic.
And use memzero_explicit for better clearing of sensitive data.
Note unlike other patches in this series this commit actually makes
functional changes to the sha256 code as used by the purgatory code.
This fully aligns the lib/crypto/sha256.c sha256 implementation with the
one from crypto/sha256_generic.c allowing us to remove the latter in
further patches in this series.
