[U-Boot] [PATCH 4/5][v3] armv8/ls1043ardb: SECURE BOOT target added for NOR
LS1043ARDB Secure Boot Target from NOR has been added. - Configs defined to enable esbc_validate. - ESBC Address in header is made 64 bit. - SMMU is re-configured in Bypass mode.
Signed-off-by: Aneesh Bansal aneesh.bansal@freescale.com --- Changes in v3: - Enabled CONFIG_SYS_NS16550=y, CONFIF_DM=y and other options similar to ls1043ardb_defconfig. - fsl_secure_boot.h is included outside of ifdef in file include/configs/ls1043ardb.h
