> From: Marcel Ziswiler <marcel.ziswiler at 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:
> Taken from NXP's commit 56d2050f4028 ("imx8m: Add DEK blob encapsulation
> for imx8m").
