9a3454d695 Touch code cleanup, stop scanning when no touch.
No need to change voltages on touch panel when no touch is detected. This should reduce noise a bit.

f1ca3fe5bb Switch RFFC5072, MAX2837 back to 40MHz reference.
Turns out the MAX2837 can't tune the necessary range when given a 50MHz reference. Oops.

19764ce693 Swap function of P2_8, P2_4 in schematic, firmware, CPLD.
gpio_unused: P2_4 -> P2_8
gpio_lcd_rd: P2_8 -> P2_4
P2_8 is a very long line, shared with DFU button.
Revise schematic to match CPLD signal names.

Jared Boone
d8b3b4cb6b Check queue empty only once when reading messages.
There was a second is_empty() call hidden in the pop() call, so the while(condition) was redundant.

5d9079f87f Stop streaming when changing baseband configuration.
Without, the baseband would get confused.

035ec84f04 Wrap MessageQueue.push() with mutex.
This addresses issue #61, occasional FIFO/data corruption. With the mutex, any thread on one core can write to the FIFO. But still, only one thread on one core should read from the FIFO.

7937ea7327 Enable DMB instruction at end of FIFO data copy.
Can't hurt to make sure FIFO and buffer state are flushed before returning to caller...
