skiboot-5.4.11 was released on Wednesday Dec 4th, 2019. It replaces
:ref:`skiboot-5.4.10` as the current stable release in the 5.4.x series.

Over :ref:`skiboot-5.4.10`, we have below bug fix to support inband ipmi
interface:

- FSP/IPMI: Handle FSP reset reload
  FSP IPMI driver serializes ipmi messages. It sends message to FSP and waits
  for response before sending new message. It works fine as long as we get
  response from FSP on time.

  If we have inflight ipmi message during FSP R/R, we will not get resonse
  from FSP. So if we initiate inband FSP R/R then all subsequent inband ipmi
  message gets blocked.

  Sequence:
    - ipmitool mc reset cold
    - <FSP R/R complete>
    - ipmitool <any command> <-- gets blocked

  This patch clears inflight ipmi messages after FSP R/R complete.
