From: Vinitha Pillai-B57223 Date: Wed, 22 Nov 2017 05:08:35 +0000 (+0530) Subject: SECURE BOOT: Add fall back option X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9b457cc6d16dadc29f3e7ed560171a9a20b9c5d7;p=u-boot.git SECURE BOOT: Add fall back option Add fall back option, to boot from NOR/QSPI/SD for LS1043, LS1046, LS1021 in case of distro boot failure. For LS1046, add kernel validation in case of secure boot in sd_bootcmd and qspi_bootcmd. For LS1043 and LS1021, add kernel validation in case of secure boot in sd_bootcmd, qspi_bootcmdand nor_bootcmd.
