So CONFIG_DM needs to be enabled by default for this 1173223f0eSSimon Glass library to function. 1273223f0eSSimon Glass The signing part is build into mkimage regardless of this 1373223f0eSSimon Glass option. The software based modular exponentiation is built into 1473223f0eSSimon Glass mkimage irrespective of this option. 15d9f23c7fSRuchika Gupta 1651c14cd1STeddy Reedconfig SPL_RSA 1751c14cd1STeddy Reed bool "Use RSA Library within SPL" 1851c14cd1STeddy Reed depends on RSA 1951c14cd1STeddy Reed 20d9f23c7fSRuchika Guptaif RSA 21d9f23c7fSRuchika Guptaconfig RSA_SOFTWARE_EXP 22d9f23c7fSRuchika Gupta bool "Enable driver for RSA Modular Exponentiation in software" 23d9f23c7fSRuchika Gupta depends on DM && RSA 24d9f23c7fSRuchika Gupta help 25d9f23c7fSRuchika Gupta Enables driver for modular exponentiation in software.
