Out-of-band SRESET

[Ananth N Mavinakayanahalli]

Hi,

One requirement from a OpenPOWER service point-of-view is to be able to
trigger an out-of-band SRESET on a unresponsive system. We can then have
the necessary plumbing in the host Linux kernel to either drop the
machine into a debugger or trigger a dump capture, if configured.

On P9, this would translate to a series of SCOM operations for the SBE
It would be good to have a REST API defined to cater to this specific
purpose.

The API should cater to:
- SRESET a core
- SRESET a chip
- SRESET all cores

Thoughts?

Regards,
Ananth
