 In principle any suitable algorithm can be used to sign and verify a hash.
-At present only one class of algorithms is supported: SHA1 hashing with RSA.
-This works by hashing the image to produce a 20-byte hash.
+U-Boot supports a few hashing and verification algorithms. See below for
 While it is acceptable to bring in large cryptographic libraries such as
 openssl on the host side (e.g. mkimage), it is not desirable for U-Boot.
