 * The following table holds all device probe functions

 * shift:  number of continuation bytes before the ID
 * idcode: the expected IDCODE or 0xff for non JEDEC devices
 * probe:  the function to call
 *
 * Non JEDEC devices should be ordered in the table such that
 * the probe functions with best detection algorithms come first.
 *
 * Several matching entries are permitted, they will be tried
 * in sequence until a probe function returns non NULL.
 *
 * Probe functions will be given the idcode buffer starting at their
 * manu id byte (the "idcode" in the table below).  In other words,
 * all of the continuation bytes will be skipped (the "shift" below).
