[U-Boot] Is RSA algorithm support for the software authentication in u-boot?

[Surendra Barku Dhobale]

Hi ,
        I am looking for the RSA , public key authentication  for the images like u-boot.img ,uImage from the u-boot. In u-boot already  support for the SHA1 and md5,that's great!!!. But I want to use RSA algorithm for more security and official firmware releases.
Is there any support for that in u-boot?.  Or we have to integrate it.?
Please gives us the suggestions...

Surendra.
