Hi all,

I just resurrected the target-avr patchset from Michael Rolnik. Following the details:

commit f2bca179dbfc3f378b131ed619d07db946bae598
Merge: 43771d5 ed250c0
Author: Ani Chang <anichang@protonmail.ch>

target/avr: resurrected (see mailing list qemu-devel, Richard Henderson on Sep 20, 2016 at 8:35pm)
and fixed (it builds).

Details:
- merge remote git://github.com/rth7680/qemu.git tags/pull-avr-20160920 into master
- fixed include/sysemu/arch_init.h (i.e.: bump QEMU_ARCH_AVR from 1<<17 to 1<<18)
- fixed target/avr/cpu.c (i.e.: remove one function arg)
- fixed target/avr/machine.c (i.e.: fix a bunch of getters/setters signatures)

Running the sample board outputs:

$ ./qemu-system-avr
Unexpected error in object_property_add() at qom/object.c:940:
qemu-system-avr: attempt to add duplicate property 'memory' to object (type 'avr5-avr')
Aborted (core dumped)

I have no idea what to do from here. How to solve the "attempt to add duplicate property 'memory' to object" error?

Regards
