Subject[GIT PULL] FSI updates
Hi Greg !

There are a first round of updates of the FSI stack, aiming at reducing/removing
the gap with the OpenBMC tree and a first step in getting dependent drivers

These changes significantly improve the FSI bitbanging driver performance
and reliability, and add the new "sbefifo" driver for communicating with
the POWER9 Self Boot Engine (which will be needed for some upcoming
additional drivers).

[ Apologies if I got part of the process wrong, I haven't
sent a pull request in years ;-) ]


The following changes since commit 8efcf34a263965e471e3999904f94d1f6799d42a:
