eepromread: simple program to view eeprom contents This program uses the i2c /dev interface to read the contents of EEPROMs and display it to the user in HEX and ASCII. It also has a mode that can display data in label:value pairs. That mode is used for board detection in the rc script to start the right i2c drivers for the board.

eepromread: support for reading from /dev/eeprom eepromread could only read EEPROMs through the /dev/i2c interface. Once the cat24c256 driver is started and claims/reserves the device, it can no longer be read through the /dev/i2c interface. This patch adds support for reading from EEPROMs through the /dev/eeprom interface. For example, to read the on-board eeprom on the BBB, one would do `eepromread -f /dev/eepromb1s50 -i`.
