[flashrom] [Ubuntu] Dediprog SF100 support with Winbond W25Q64FW

[Kurt Qiao]

Hi Carl,

  i found dediprog_spi_send_command in dediprog.c, after below action:

 ret = usb_control_msg(dediprog_handle, 0xc2, 0x01, 0xbb8, 0x0000,
                 (char *)readarr, readcnt, DEFAULT_TIMEOUT);

 readarr will become 0x534631 ("SF1"), even i didn't put a ROM on my SF100.

  i have no idea about this usb device request, the meaning of wValue 0xbb8
to dediprog device
hope this info help for debug, thanks.

BR,
Kurt
