Shoot.... most of what I wrote got trimmed accidentally.  Here's the
rest of the text:

However, I've completely devoted to this work for at least the next
two months, so there are plenty more patches to follow.  Once I've
got all the common code merged between Microblaze, PowerPC and Sparc
I'll be fix the endian problems and making it easily usable by other
architectures like ARM and MIPS.  Lots of work to be done.

As for merging this stuff, because the patches cross architecture
boundaries, I've been thinking of publishing a new git tree for
collecting device tree related changes and getting it added to the
linux-next tree list.  I'll commit changes to that tree once I get
acks from each of the affected arch maintainers.  Then, either Linus
can pull my tree directly, or I could ask a more senior maintainer
to pull into their tree before sending a pull request to Linus.  Ben,
David and Michal, how does that sound to you?  Stephen, would you be
willing to add my tree to the linux-next list?

Also, I'd like to take on responsibility for maintaining the cross-
architecture device tree code.  If there are no objections, I'll
write a patch to add a device tree section to MAINTAINERS.

Cheers,
g.
