This is the AVR port from Michael, release (merge) candidate 6. I've rebased rc5 to the current master branch, fixed the conflicts, and updated the APIs where necessary (e.g. qdev_create() had to be replaced).
These patches have been on the list for a long time. Let's try to get them finally merged. You can also find the patches in my repo here: https://gitlab.com/huth/qemu/-/tree/avr rc6: - Rebased to master, fixed conflicts - Changed the object_initialize_child() and qdev_create() calls where necessary - Converted the texi doc to Sphinx - Dropped the travis.yml patch - the acceptance CI is currently moved to gitlab, so we should add it later there instead - Dropped the patch to clean up MAINTAINERs - and do it correctly right from the start instead.
