RSA support. This enables the RSA algorithm used for FIT image

verification in U-Boot.

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.

The standard RSA-signature verification code (FIT_SIGNATURE) uses
|
|
pre-calculated key properties, that are stored in fdt blob, in
|
|
decrypting a signature.
|
|
This does not suit the use case where there is no way defined to
|
|
provide such additional key properties in standardized form,
|
|
particularly UEFI secure boot.
|
|
This options enables RSA signature verification with a public key
|
|
directly specified in image_sign_info, where all the necessary
|
|
key properties will be calculated on the fly in verification code.
