avr: add attiny1616 support This is just support for the chip, no boards are currently supported. However, you can use this target on a custom board. Notes: - This required a new runtime and machine implementation, because the hardware is actually very different (and much nicer than older AVRs!). - I had to update gen-device-avr to support this chip. This also affects the generated output of other AVRs, but I checked all chips we support and there shouldn't be any backwards incompatible changes. - I did not implement peripherals like UART, I2C, SPI, etc because I don't need them. That is left to do in the future. You can flash these chips with only a UART and a 1kOhm resistor, which is really nice (no special hardware needed). Here is the program I've used for this purpose: https://pypi.org/project/pymcuprog/
