[Skiboot] [PATCH V3 0/6] opal/errorlog : Generalize errorlog read/write routines and adds write to host support for BMC systems

[Mukesh Ojha]

Improve current errorlog infrastructure by splitting existing FSP specific
errorlog read/write routines into common and hardware(FSP) specific routines.
This would add errorlog writing to host support for BMC based platforms.

It involves movement of some functions from FSP specific fsp-elog-write.c
and fsp-elog-read.c files to core/elog-host.c .Introduction of platform
hooks for elog info, ack, read and resend pending logs.

Patch 1 does function movement related to write to host path.

Patch 2 does some modification related to alignment, typo mistakes and
upper-lower case issues etc.

Patch 3 resolves the bug of not clearing the variable OPAL_EVENT_ERROR_LOG_AVAIL
properly.

Patch 4 does movement of opal registration of callbacks from fsp-elog-read.c
to generic core/elog-host.c. Detailed described in the individual patch.

Patch 5 Introduces the reference count field in errorlog structure and addition
of put_elog, get_log routine, which will be used in later patch.

Patch 6 adds the support of errorlog write to the host for BMC systems
using generic framework.
