hw/avr: Introduce few Arduino boards Hi, This series add the arduino boards, aiming at removing the 'sample' board that doesn't follow any specification. Since v3: - Rebased on Michael's v41 - Drop 'extram' unused field (Igor) - Renamed devices AVR -> Atmel (Aleksandar) (I haven't renamed structure names to ease review) Since v2: - rebased on Michael's v40 Since v1: - Addressed Igor comments - Addressed Aleksandar comments - Fixed UART issue (was due to IRQ shifted by 2 in CPU) Since Michael's work is not yet merged, Various of my patches - which are trivials or simple renames - could be squashed directly on his patches, if we ever care. [I believe sending this patches is easier/quicker than keeping asking Michael to respin his series infinitely]. Michael, do you mind testing it?
