  6. RSA support. This enables the RSA algorithm used for FIT image
  7. verification in U-Boot.
  8. See doc/uImage.FIT/signature.txt for more details.
  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.

  22. Enables driver for modular exponentiation in software. This is a RSA
  23. algorithm used in FIT image verification. It required RSA Key as
  24. input.
  25. See doc/uImage.FIT/signature.txt for more details.

  29. help
  30. Enables driver for RSA modular exponentiation using Freescale cryptographic
  31. accelerator - CAAM.
