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