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.

# We are going to use COTS FT2232D breakout boards in the MCU host bus # emulation mode (enabled at run time via libftdi, cannot be configured # in the EEPROM) to drive several different candidate 176x220 pix TFT LCDs # (8-bit parallel 8080-style interface) as part of our LCD evaluation # testing and vendor selection process. The purpose of this EEPROM config # with a custom FTDI PID is to keep the Linux kernel's ftdi_sio driver # from binding to this FT2232D instance, avoiding the creation of ttyUSBx # device nodes for it. vid 0x0403 # FTDI pid 0x7157 # Allocated by FTDI to Falconia Partners LLC manuf FTDI product MCU host bus emulation # Try to be nice to Weendoze lusers (or should it be Losedows?) byte00 0x00 # Channel A driver: D2XX byte01 0x00 # Channel B driver: D2XX
