Re: [PATCH] Open Firmware device tree virtual filesystem

I would not exactly call what we have for powerpc
"exporting the OFW device tree". I don't quite know
what it is, but it isn't as simple as exporting the
OFW device tree. I don't think we really wanted to
get into any of that here.

The Linux PowerPC port uses an OF-like device tree on
*every* platform, even those that don't have a native OF.
It also has to work around lots of bugs in many OF
implementations.  It's doing lots of stuff, and not all
of it is nicely separated into logical modules I'm afraid.

Sure they can take advantage of it, if what they need
to export is a read-only copy of the actual device tree
without any legacy burden or having a writable/changeable
copy of it with a trivial implementation.

So give them an interface that allows them to hook up to
your new code :-)

This is a trivial implementation that suits it's purpose.
It's simple. I'm not sure what more is needed for this
project when it's pretty clear that i386 will never need
any additional support for open firmware.

Never say never...
