This patch series defines generic interfaces for error logging to
push down critical errors from powernv platform to FSP.
Also, it contains few minor fixes for the exisiting error logging
framework that retrieves error logs from FSP.
Changes from V4:
* Reverted OPAL token for ELOG_OPAL_SEND to 92
* Use __pa() to obtain the physical address of the error log
buffer.
Changes from V3:
* Change memory allocation to GFP_ATOMIC, to generate
errors in bad context
* Move all error log generation related code to arch/powernv
rename it from opal_* to pnv_* .
Changes from V2:
* Review comments from V2 have been addressed
includes comment formats, changing naming
conventions and incorporated error handling
of the buffers.
* Minor typo fix and use of pr_err/pr_fmt to
log errors.
