Sorry, I missed a word: "with chromeos update mechanism". […]
Okay, so you want to dual-boot, and you want ChromeOS to keep updating at the same time? That is indeed tricky. If you want to receive ChromeOS firmware updates and actually apply them then you will have to base the custom coreboot you're building on the appropriate ChromeOS firmware branch for your board, I think that's the only realistic way to make sure they're compatible. But do you really need firmware updates? We don't really send them out that often (especially if the board is older), and most of the time they are minor fixes or security things that wouldn't really make much of a difference if you're already running in such a makeshift unsupported configuration.
Would it be enough if we just allowed you (in developer mode) to configure the ChromeOS updater such that it will only apply kernel and rootfs updates, but not firmware updates? I can't promise anything but I could ask if that's a feature we could add.
