- * Description:
- *
- * This code reads the ATMEL 24CXX EEPROM. The PMC-Sierra Yosemite board uses the ATMEL
- * 24C32/24C64 which uses two byte addressing as compared to 24C16. Note that this program
- * uses the serial port like /dev/ttyS0, to communicate with the EEPROM. Hence, you are
- * expected to have a connectivity from the EEPROM to the serial port. This program does
- * __not__ communicate using the I2C protocol
