Linux I2C slave eeprom backend

==============================



by Wolfram Sang <wsa@sang-engineering.com> in 2014-15



This is a proof-of-concept backend which acts like an EEPROM on the connected

I2C bus. The memory contents can be modified from userspace via this file

located in sysfs:



	/sys/bus/i2c/devices/<device-direcory>/slave-eeprom



As of 2015, Linux doesn't support poll on binary sysfs files, so there is no

notfication when another master changed the content.
