RSA support. This enables the RSA algorithm used for FIT image
verification in U-Boot.
See doc/uImage.FIT/signature.txt for more details.
+ The Modular Exponentiation algorithm in RSA is implemented using

+ The signing part is build into mkimage regardless of this
+ option. The software based modular exponentiation is built into
+ mkimage irrespective of this option.
