Query/plan about ARM targets RTEMS integrated debugging

[Yanjun Luo]

Hi Pavel,

I really glad that someone has this plan. Although I have no experience
about GDB stub,  I really like to do something about this.
I have several experience at AT91RM9200 running RTEMS, but
it's really painful I can't debug at all.
printf/printk is not a very efficient way.

Regards,
Yanjun Luo.
