Enable this to support SHA256 checksum of FIT image contents. A
SHA256 checksum is a 256-bit (32-byte) hash value used to check that
- the image contents have not been corrupted. SHA256 is recommended
- for use in secure applications since (as at 2016) there is no known
- feasible attack that could produce a 'collision' with differing
- input data. Use this for the highest security. Note that only the
- SHA256 variant is supported: SHA512 and others are not currently
- supported in U-Boot.
