ARM Getting Started Assistance: Beagleboard, Zedboard, or STM32F4Discovery?

Aha, the rosetta stone.  I couldn't figure out how to release the CPU,
since typing 'c' to continue at the console does nothing.  Maybe it is
really waiting for GDB's 'continue' command instead of 'c' at the
monitor console.  At any rate, the core problem is that in this BSP it
is serial1, not serial0 which is directed to the RTEMS console.  I
don't know if that is standard or not.  These documentation changes
describe how I got the example programs to work on the
xilinx_zynq_a9_qemu BSP.
