It is relatively straightforward to add new algorithms if required. If
another RSA variant is needed, then it can be added to the table in
image-sig.c. If another algorithm is needed (such as DSA) then it can be
placed alongside rsa.c, and its functions added to the table in image-sig.c
also.

it can be placed in a directory alongside lib/rsa/, and its functions added
using U_BOOT_CRYPTO_ALGO().
