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 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
