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 DUART28S
# configuration sets the default USB ID that is used by FT2232x adapters
# and is recognized and treated as a generic dual UART device by the
# standard unpatched Linux kernel ftdi_sio driver.  This configuration
# is intended for those users who don't need DUART28C boot control outputs
# and who wish to avoid the major inconvenience of applying a custom patch
# to their Linux kernel ftdi_sio driver.  Please note that boot control
# outputs CTL1 and CTL2 cannot be used with this EEPROM configuration -
# they will be triggered whenever Channel B ttyUSBx device is opened,
# making them unusable.
