Failover and Fallback

[Harald Gutmann]

Hello,

I know how the coreboot image is scaled with Failover/Fallback/Normal.
http://www.coreboot.org/Anatomy_of_a_Failover_coreboot_v2_Image

But my question is when does coreboot access Failover or Fallback?
I wasn't able to determine that, but it would be good to know.

Kind regards,
Harald

Only some boards have Failover.

Failover chooses whether to boot Normal or Fallback, based on whether the
last boot was successful.

Look in cache_as_ram_auto.c or auto.c for your board.

Thanks,
