Is anyone working on getting RTEMS running on Cortex-M3?  The last I saw
on the list (this list, the LinkedIn list has been really quiet) was a
mention to "make sure the processor is supported by the cpukit".  It
looks like the relevant directory would be rtems/cpukit/score/cpu/arm.

I've never worked in this part of the RTEMS source before and this is my
first time working with ARM.  I'm starting to wonder if a new directory
would be a good idea since the Cortex-M3 doesn't have the ".arm" mode
and always stays in ".thumb" mode; perhaps
