qemu-arm: Rework to run bare-metal on boards with Cortex-M CPUs. Adds support for 3 Cortex-M boards, selectable via "BOARD" in the Makefile: - microbit, Cortex-M0 via nRF51822 - netduino2, Cortex-M3 via STM32F205 - mps2-an385, Cortex-M3 via FPGA netduino2 is the default board because it's supported by older qemu versions (down to at least 2.5.0). 2018-09-23 22:09:28 -04:00			`void uart_init(void);`
