PS1, Line 9: Solve NVM not working
> What does not work exactly?

Currently, we set in coreboot to create NVM file nodes normally, but it’s failed to dump the nvm data by test command.

# cat /sys/bus/i2c/devices/i2c-PRP0001:01/eeprom > ./ov8856_eeprom_test.bin
  # hexdump -C ./ov8856_eeprom_test.bin > ov8856_eeprom_dump.log
  # cat ov8856_eeprom_dump.log

It will report the following error:
cat: '/sys/bus/i2c/devices/i2c-PRP0001:01/eeprom': Connection timed out
