FYI, if you have patches for arch/powerpc, I recommend that=20 you submit them to linuxppc-dev. linuxppc-embedded is not=20 monitored by many important people including paulus.
=20
Since these are 8xxx patches, chances are Kumar will see them=20 and take them but you're still better off submitting to linuxppc-dev. =20

Thanks for the advice, but I was just basing the list to post to on the MAINTAINERS file which states that this is the one for Embedded PPC83XX. If you still think that I should post to linuxppc-dev, let me know.

Yes, I think it would be better to repost to linuxppc-dev.

Does anyone have an objection to changing all of the:

in MAINTAINERS to:

	"L:	[email protected]" ??

I personally don't care either way. I'm already subscribed to both lists.

Makes sense to go to linuxppc-dev given the arch/powerpc migration.

I thought the -embedded list was created in the first place to keep some of the "noise" off of -dev (i.e. "I can't get interface <foo> to work on my custom <embedded eval board>-lookalike board, HELP!"). If people still care about keeping that on a separate list, then we shouldn't change it.

I think the relevant people probably monitor this list (maybe not quite as frequently) to catch things. I even caught the first PWRficient-related question in a timely manner the other day. :-)

Still, that being said, patches will clearly get better exposure on -dev, especially device tree crap.

Yes, IIRC, that was the reason but now with the merge and low volume on this list, it makes sense to me to just get rid of -embedded.

Perhaps my perspective is unique, but I doubt it. I find it nice that this list is low volume and not filled with endless patches about CHRP and P series and open firmware syntax blah blah blah...

No offense intended to all the people who are doing wonderful work expanding the Linux universe, but for your average dude or dudette working on embedded boards that happen to have a PowerPC processor, this list is a pretty good forum.
