Are SGKs for secure boot signatures now supported in imx93 or still only SRKs?
Application note 12312 "Secure Boot on AHAB Supported Devices" says in Chapter 3:
Note: For i.MX8ULP and i.MX93, only SRK is supported in the current released firmware.
Is this still true or are SGKs supported now? If so, from which firmware release?
