Hello all,

This series implements a basic exception handler and the required
support infrastructure on Power. Currently the handler just dumps all
registers to the serial console and nothing else, but even this is
useful for debugging during early bring-up.

An additional patch to fix the stack setup code in head.S is also
included.

Thanks,
