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