Simon Glasse3ee2fb2016-02-22 22:55:43 -07009 The Modular Exponentiation algorithm in RSA is implemented using
10 driver model. So CONFIG_DM needs to be enabled by default for this
11 library to function.
12 The signing part is build into mkimage regardless of this
13 option. The software based modular exponentiation is built into
14 mkimage irrespective of this option.
