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.
