target, use for overlays + +Change the filenames and extensions to keep the pre-DDT style of +overlay (<name>-overlay.dtb) distinct from new ones that use a +different style of local fixups (<name>.dtbo), and to match other +platforms. + +The RPi firmware uses the DDTK trailer atom to choose which type of +overlay to use for each kernel. + +Signed-off-by: Phil Elwell
