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