Subject: [PATCH v1 4/7] ARM: dts: imx8mm-verdin: prepare for dek blob encapsulation
Date: Fri, 20 Aug 2021 22:52:27 +0200 [thread overview]
Message-ID: <20210820205230.1369683-5-marcel@ziswiler.com> (raw)
In-Reply-To: <20210820205230.1369683-1-marcel@ziswiler.com>
From: Marcel Ziswiler <marcel.ziswiler@toradex.com>
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").
