Hi PPC Maintainers,
We are seeking feedback on the status of relaxed write API implementation.
What is the motivation for not implementing the relaxed API?
I see that network drivers are working around the issue by calling
__raw_write() API directly but this also breaks other architectures
like SPARC since the semantics of __raw_writel() seems to be system dependent.
This is putting drivers into a tight position and they cannot achieve true
multi-arch enablement and are forced into calling __raw APIs flavors
directly with #ifdef BIG_ENDIAN ugliness.
