Depends on #193.
This branch brings up an initial working MnemOS kernel for the ESP32-C3,
with a working scheduler/timer run loop. The timer handling hasn't been
thoroughly tested for accuracy, and some of my math might be wrong, but
it does run stuff. Currently, no driver exists for the USB JTAG serial
device, so we can only see output from
esp-println, not from thekernel trace service. But, it does work!
I've also split the
mnemos-esp32c3-buddycrate into separateqtpyand
xiaobin targets, because it turns out these two boards havedifferent pin mappings --- despite the boards themselves being
pinout-compatible, the MCU's GPIO pins are routed differently.
