Typically these are the options that one has to select in menuconfig. But in order to have them work as expected you need few other things. As a reference please heave a look at: https://review.coreboot.org/c/coreboot/+/35998
You need to reserve some CMOS memory for vboot context, set default vboot configuration in Kconfig of your platform and prepare a flashmap layout file (*.fmd) - its the simplest case. Additionally you should have at least one RW slot by selecting CONFIG_VBOOT_SLOTS_RW_A.
If this is already done for your boards, then: CONFIG_VBOOT CONFIG_VBOOT_MEASURED_BOOT CONFIG_VBOOT_SLOTS_RW_A
selected from menuconfig should be sufficient.
Wow, it seems a little more complicated than get some pointers and extend them :) Well, thanks for the info! I'll give it a try!
