| The Modular Exponentiation algorithm in RSA is implemented using | |
| driver model. So CONFIG_DM needs to be enabled by default for this | |
| library to function. | |
| The signing part is build into mkimage regardless of this | |
| option. The software based modular exponentiation is built into | |
| mkimage irrespective of this option. | |
