* 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.
*
* IDCODE_CONT_LEN may be redefined if a device needs to declare a
* larger "shift" value. IDCODE_PART_LEN generally shouldn't be
* changed. This is the max number of bytes probe functions may
* examine when looking up part-specific identification info.
*
* 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).
