[PATCH v2 0/2] PBL: add support for optimized sha256

When chainloading a full barebox from the PBL we have to verify the
loaded image with sha256. This can take some time for bigger image, so
add support for optimized implementations and ad the ARM64 Crypto
Extensions as a first implementation

- drop ARMv8 specific comment in generic file
- Use static SHA256_DIGEST_SIZE in function prototype
- Link to v1: https://lore.barebox.org/[email protected]
