I wouldn't craft a sanity check through user action (having to specify the I/O port pair) but having a list of supported EC's sounds like a good idea but I wonder if we should check the chip id or better the firmware id (e.g. the "ITE string" or sth else) because support for this firmware-based programming mechanism is implemented in EC fw. The other approach is direct flashing via the flash registers (see it85spi.c, it87spi.c for example), which *should* also work on various ITE ec's even without firmware support.
