// modified (allowing the SPI and debug to always be accessible unless
// overridden by a flash program).

// The values below can be any of the standard types defined above,
// or they can be any 13-bit value if the user wants a non-standard
// startup state for the GPIO.  By default, every GPIO from 5 to 37
// is set to power up as an input controlled by the management SoC.
// Users may want to redefine these so that the user project powers
// up in a state that can be used immediately without depending on
// the management SoC to run a startup program to configure the GPIOs.
