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
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.
17 config RSA_SOFTWARE_EXP
18 bool "Enable driver for RSA Modular Exponentiation in software"
21 Enables driver for modular exponentiation in software. This is a RSA
22 algorithm used in FIT image verification. It required RSA Key as

26 config RSA_FREESCALE_EXP
27 bool "Enable RSA Modular Exponentiation with FSL crypto accelerator"
28 depends on DM && RSA && FSL_CAAM
30 Enables driver for RSA modular exponentiation using Freescale cryptographic
