[Pdbg] [PATCH 00/19] Basic gdbserver for POWER8

[Rashmica Gupta]

I have rebased Alistair's gdbserver on master and done a few cleanups.
I have been using Amitay's patch "main: Add P8 kernel devicetree" when
running on a BMC.

This should let you do basic things through gdb like examine the
registers, read and write to kernel memory, and step through the
kernel. There is obviously a lot more to be done, but it would be nice
to get some of this upstream so I don't have to keep rebasing as often :)

Currently this is only designed to work on kernel addresses (as the
translation to real addresses is trivial). Any thoughts on how we
could/should go about dealing with address translations are welcome.
It would be nice if we could attempt to deal with kernel virtual
addresses and skiboot addresses.
