Hi All,
We are trying to implement HABv4 on an IMX8M Mini based target.

correction: if (b) is not available
need to add/change these two configs for IMX8M Mini: CONFIG_IMX_CONTAINER_CFG CONFIG_SYS_EXTRA_OPTIONS (reference: board/freescale/imx8qm_mek)
d. doc/imx/habv4 talks with reference to imx6,7. Are there any other items I need to take care of when working on IMX8M Mini secure boot:
Please suggest how should we go about.
Thanks and Regards
