Created attachment 193990 [details] diff to add mu driver Add support for the bcm2835-aux-uart. BUGS baud rate locked to 115000 CPU clock assumed to be locked to 250 Mhz
should also work on RPi1 and RPi2 as well since they have similar hardware for bcm2835. however, RPi1 may not expose the 'aux' serial port pins easily. recommend adding this to armv6 and armv7 as well
