[Skiboot] [PATCH V2 0/6] opal/errorlog : Generalize error log read/write routines and adds error log 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 hw (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.
