Two new mailing lists have be created at avr32linux.org: "kernel" for Linux kernel stuff and "u-boot" for u-boot stuff. Please see the following page for more information:
The mailing lists are meant to supplement the avrfreaks.net forums, not replace them. In particular, the avrfreaks forums have turned out to be not very suitable for posting patches -- it's difficult to get them attached properly, it's not straightforward to discuss them afterwards and they tend to be lost in the noise. So the new mailing lists are meant primarily for posting and discussing patches, but testers are more than welcome too.
Please note the rules for those mailing lists -- they are few, shouldn't be difficult to follow, and open for discussion (they're written on a wiki page after all.)
So if you've written or improved a driver, please post a patch to the appropriate list and we will help you review and get it passed on to the higher levels in the hierarchy.
