hw/avr: Add limited support for some Arduino boards
Arduino boards are build with AVR chipsets. Add some of these boards: - Arduino Duemilanove - Arduino Uno - Arduino Mega For more information: https://www.arduino.cc/en/Main/Products https://store.arduino.cc/arduino-genuino/most-popular [AM: Remove word 'Atmel' from filenames and all elements of code] Suggested-by: Aleksandar Markovic <[email protected]> Signed-off-by: Philippe Mathieu-Daudé <[email protected]> Signed-off-by: Richard Henderson <[email protected]> Signed-off-by: Aleksandar Markovic <[email protected]> Reviewed-by: Igor Mammedov <[email protected]> Reviewed-by: Joaquin de Andres <[email protected]> [thuth: sysbus_init_child_obj() ==> object_initialize_child()] Signed-off-by: Thomas Huth <[email protected]> Message-Id: <[email protected]>
