17:39 <gordanb> Does anyone know how to set dev_boot_usb without being in ChromeOS on a Chromebook 2? I have long blown that away and am running regular Linux, but I wanted to boot off the SD card to test a newer distro, and I'm finding that Ctrl-U tells me to go away because USB booting isn't enabled.

17:40 <gordanb> I can see that crossystem binary I salvaged from the ChromeOS install way back then tries to open /proc/device-tree/firmware/chromeos/nonvolatile-context-{lba|offset|storage}, but that doesn't exist on my mainline kernel.

17:41 <gordanb> So can anyone tell me what bit I need to flip and where on mmc0 to enable that flag?
