[coreboot] Re: How to measure the differents parts of coreboot?

Hi Michal!

Thanks for the info!

Yes, I'm using the amd/bettong mainboard. I've changed the Kconfig adding

config VBOOT
    select VBOOT_STARTS_IN_ROMSTAGE
    select VBOOT_NO_BOARD_SUPPORT
    select VBOOT_MEASURED_BOOT
    select AMDFW_OUTSIDE_CBFS

config VBOOT_SLOTS_RW_A
    default y

config FMDFILE
    string
    default "src/mainboard/$(CONFIG_MAINBOARD_DIR)/vboot-rwa.fmd" if VBOOT

Now, I get an error processing the CBFS. As you said, I suppose I need to modify the sizes
to adapt it to my requirements. Where can I found info about the fmap files? This, and the
cmos layout files are unknown areas to me, and I don't know where to begin to modify it.

The error I get is:
