[rtems commit] tests: atomic support for RTEMS. Uniprocessor tests for atomic ops.

[Claus, Ric]

Xilinx ZYNQ (dual core Cortex-A9).  I'm currently working on an RTEMS BSP for it and trying to understand the existing ARM support.

It is very easy to port the current SMP implementation of RTEMS to new
architectures.  You just have to provide the basic BSP support for
initialization of secondary processors and the
_CPU_Context_switch_to_first_task_smp() and SMP_CPU_SWAP() CPU port definitions.

Which chip do you intend to use?
