config ASPEED_HACE bool "ASPEED Hash and Crypto Engine" depends on DM_HASH help Select this option to enable a driver for using the SHA engine in the ASPEED BMC SoCs. Enabling this allows the use of SHA operations in hardware without requiring the SHA software implementations. It also improves performance and saves code size. config ASPEED_ACRY bool "ASPEED RSA and ECC Engine" depends on ASPEED_AST2600 help Select this option to enable a driver for using the RSA/ECC engine in the ASPEED BMC SoCs. Enabling this allows the use of RSA/ECC operations in hardware without requiring the software implementations. It also improves performance and saves code size.
