Hi,
I'm currently working on the backlog we have with patches and wanted to point out a nice tool we have for that.
On http://patchwork.coreboot.org/project/coreboot/list/ you can find a patchwork installation which tracks our mailing list, keeping watch over submitted patches and the discussions related to them.
Please feel encourage to look there for patches that seem to be forgotten, and review them, bring them alive again, and make sure, they can get in (or get improved on, if they need more work).
Patches that are sufficiently processed (accepted/committed, rejected, superseded, etc) disappear from view, so as long as the default view on that page lists patches, there's still a patch that waits for someone to take care of it.
It's also a good place to keep track of the patches you submitted over time, to see if they're in already. The patch list should be quite recent about which patches are in and which aren't.
If you require additional privileges on patchwork, please tell me, and I'll set things up appropriately.
Patrick
