qi-add-noboot-and-append-check.patch
This adds two features that can be set in the rootfs that Qi is checking. - if it finds /boot/noboot-<device>, eg /boot/noboot-GTA02 then it will skip the rootfs for booting and try the next one if any - if it finds /boot/append-<device>, eg, /boot/append-GTA02 then it will append the contents of this file to the kernel commandline.
