fc-duart28-conf: replace find and check-eeprom with single show command
The original design with separate find and check-eeprom commands
was driven by the assumption that we had to bump off the ftdi_sio driver
in order to read the EEPROM, while a USB device tree check could be done
non-invasively. However, now that we know that we can read the EEPROM
non-invasively too, we can simplify the tool with a single show command.

# This EEPROM configuration is one of two possible configs that can be # programmed into FreeCalypso DUART28 adapters (custom hw made by # Falconia Partners LLC) based on the FT2232D chip. The present DUART28C # configuration sets a custom USB ID and is intended to be used together # with a custom patch to the Linux kernel ftdi_sio driver that applies # a special quirk when this USB ID is detected. The driver quirk in # question applies only to FT2232D Channel B and suppresses automatic # assertion of DTR & RTS when the corresponding ttyUSBx device is opened; # this driver quirk is required in order to use the DUART28C adapter's # boot control outputs. vid 0x0403 # FTDI pid 0x7152 # Allocated by FTDI to Falconia Partners LLC manuf FreeCalypso product DUART28C
