This patchset adds support for POWER10 (P10) processor to libpdbg.
Starting from P10, most of the hardware accesses from BMC go via sbe.
This is implemented as a seperate sbefifo backend.  On a secure P10
system, raw devices used by kernel driver will not work and all hardware
access (except fsi) must go via SBE.

SBEFIFO library is updated to deal with slightly different conventions between
P9 and P10 when specifying core ids.  New chip-ops are added to SBE to read
scoms from ocmb.

Alistair Popple (3):
  libpdbg: Introduce p10 FAPI targets and address translation
  dts: Add p10 targets to device tree
  tests: Add fapi p10 address translation tests
