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