| 6 | RSA support. This enables the RSA algorithm used for FIT image | |
| 7 | verification in U-Boot. | |

9 | 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. | |

| 25 | Enables driver for modular exponentiation in software. This is a RSA | |
| 26 | algorithm used in FIT image verification. It required RSA Key as | |
| 27 | input. | |
