Hi All,

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

I have followed this discussion[1] and the patch[2]. [1] http://u-boot.10912.n7.nabble.com/Habv4-on-imx8m-tt437232.html#none [2] https://patchwork.ozlabs.org/project/uboot/patch/20210304111742.2369738-1-fe...

Here are my queries: a. IMX8M Mini doesnt support AHAB, it only supports HABv4. Is my understanding correct ?

b. Can you guys point me to any working source repo where HABv4 is tested on imx8m (Fabio talks about the vendor U-Boot code does like this, is this repo accessible ?)

c. if (a) is not available, then after applying patch[2], should we

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
