# Broadcom XLR/GTS 'eeprom' support
#
# Platform and model specific eeprom subclass, inherits from the base class,
# and provides the followings:
# - the eeprom format definition
# - specific encoder/decoder if there is special need
#
# Note: the file /usr/share/sonic/platform/sys_eeprom.bin is generated
#       by the script brcm-xlr-gts-create-eeprom-file.py
