include	drivers: dcp: add DCP support The Data Co-Processor (DCP) provides hardware acceleraiton for cryptographic algorithms. The features of DCP are: - AES128 ECB and CBC - SHA1, SHA256 - AES128-CMAC algorithm - SRAM key storage - HUK generation This driver adds DCP support for the following platforms: - imx6slevk - imx6sllevk - imx6ullevk - imx6ulzevk Signed-off-by: Remi Koman <remi.koman@nxp.com> Signed-off-by: Clement Faure <clement.faure@nxp.com> Acked-by: Jens Wiklander <jens.wiklander@linaro.org>	5 年前
dcp.c	drivers: imx: dcp: disable the use of UNIQUE KEY after HUK generation Disable the use of DCP unique key (0xfe in the DCP key selection) after the HUK generation. The DCP unique key is used to generate the HUK at boot time. Disabling the use of the unique key prevents the non-secure world from re-generating the HUK.
