Subject: [PATCH rc6 25/30] hw/avr: Add limited support for some Arduino boards
Date: Sun,  5 Jul 2020 16:03:10 +0200	[thread overview]
Message-ID: <20200705140315.260514-26-huth@tuxfamily.org> (raw)
In-Reply-To: <20200705140315.260514-1-huth@tuxfamily.org>

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Arduino boards are build with AVR chipsets. Add some of these
boards:

  - Arduino Duemilanove
  - Arduino Uno
  - Arduino Mega
