HAB failsafe mode imx8mm

Hello,

I read on the HAB API documentation that there is a failsafe mode API call from u-boot, on imx8m mini.

3.12 Failsafe mode
void(* hab_rvt::failsafe)(void)
Enter failsafe mode.

This is supposed to use an entry in a ROM table, however they don't say if the ROM table has default values and what those functions do and how to add the ROM table to u-boot.

Are there other documents or examples showing how to use this failsafe mode in practice ?

thank you
