Function riot_sys::periph_init

pub unsafe extern "C" fn periph_init()

@brief Common peripheral initialization function

This function should call all needed static initialization functions for configured peripheral drivers like SPI or I2C. This function SHOULD be called early in the boot process, e.g. before the actual kernel initialization is started.

@note This function is called by the boot up code. Application developers do not need to care. Developers porting RIOT to a new MCU must make sure that this function is called during boot up early on.
