Reviewed-by: Floris Bos Did notice the rpi-firmware package itself could use some more work. Besides the binary device tree files always being installed thing, the sample config.txt in package/rpi-firmware/config.txt also contains values that are not that suitable for the Pi 2. E.g. the Pi 2 normally runs at 900 Mhz but is being downclocked to 700 by "arm_freq=700" there. Might be better not to have any low level settings like that there, just "kernel=zImage" Yours sincerely, Floris Bos
