    stmhal: Add pyb.irq_stats() to get statistics about IRQ calls. · 401af50d
    Damien George authored
    Adds a lot of code, makes IRQs a bit less efficient, but is very useful
    for debugging.  Usage: pyb.irq_stats() returns a memory view that can be
    read and written, eg:
        pyb.irq_stats()[0] = 0
    The patch provides general IRQ_ENTER() and IRQ_EXIT() macros that can be
    modified to provide further IRQ statistics if desired.
