From 8d060e4a66d6884341fbb3d8ab1d837a3f173d47 Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Sat, 9 Oct 2021 22:41:05 +0200 Subject: [PATCH] ARM: dts: imx8mm-verdin: prepare for dek blob encapsulation Prepare for DEK blob encapsulation support through "dek_blob" command. On ARMv8, u-boot runs in non-secure, thus cannot encapsulate a DEK blob for encrypted boot. The DEK blob is encapsulated by OP-TEE through a trusted application call. U-boot sends and receives the DEK and the DEK blob binaries through OP-TEE dynamic shared memory. To enable the DEK blob encapsulation, add to the defconfig: CONFIG_SECURE_BOOT=y CONFIG_FAT_WRITE=y CONFIG_CMD_DEKBLOB=y Taken from NXP's commit 56d2050f4028 ("imx8m: Add DEK blob encapsulation for imx8m").
