Encrypt imx-boot bootloader

[vinothkumars]

Dear NXP,

Unable to boot flash.bin

U-Boot SPL 2020.04-5.4.24-2.1.0+g4979a99482 (Feb 11 2021 - 13:59:29 +0000)

Trying to boot from BOOTROM
image offset 0x0, pagesize 0x200, ivt offset 0x0
Can't support legacy image
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

I know we able to encrypt flash.bin. But, I am using imx-boot binary for bootloader for iMX8MN but, there is no guide to encrypt the imx-boot image.

Is there any guide for encrypt the imx-boot bootloader image ?

Is there any guide for encrypt the rootfs image ?

Is there any guide for encrypt the EMMC partition ?

Hello,

Please look at my comments below.

1.
There is no special guide for encrypt the imx-boot bootloader image.

2.,3.
Use AN12714 (i.MX Encrypted Storage Using CAAM Secure Keys) and
section 10.5 (Disk encryption acceleration) of i.MX Linux User's Guide.
