 	  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.
