This release adds GPIO, I2C, SPI, UART, PWM, and AnalogIn support for the Rock Pi S.
_Note: UART is untested due to issues disabling the console causing a boot loop._
It also adds a few more tools to make it easier to add other boards.
To use in CPython, `pip3 install adafruit-blinka`.
Read the [docs](https://circuitpython.readthedocs.io/projects/blinka/en/latest/) for info on how to use it.
