Use nuclei-sdk functions for init code Instead of using the HAL functions we can just use the defines from the board support for the longan nano that comes with the nuclei-sdk. Also we move some includes and defines to the header file. 2021-08-07 10:08:42 +02:00			`#include "gd32vf103c_longan_nano.h"`

Remove unsuitable clock configurations from init code Only 48MHz, 72MHz, 96MHz and 120 MHz system clocks derived from an external crystal are suitable for the usb peripheral, as the internal oscillator is not stable enough. Also the usb-prescaler only supports division by 1 (48MHZ), 1.5(72MHz), 2(96MHz) and 2.5(120Mhz). 120Mhz is also out of spec and not added here. 2021-08-07 11:03:16 +02:00			`#define __ECLIC_INTCTLBITS 4`
