The armmp kernel flavour should now support the BCM2836 and the Pi 2,
but *not* the BCM2835. Also, Debian's armhf port is built for ARMv7
whereas the BCM2835 implements ARMv6. Most of the peripherals are the
same between these two chips, so the driver names include 'bcm2835'.
I haven't yet had confirmation that it actually does work.
