2016-07-22i2c_eeprom: Add reading supportmario.six@gdsys.cc
This patch implements the reading functionality for the generic I2C EEPROM driver, which was just a non-functional stub until now. Since the page size will be of importance for the writing support, we add suitable members to the private data structure to keep track of it. Compatibility strings for a range of at24c* chips are added. Signed-off-by: Mario Six <mario.six@gdsys.cc> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de>
2014-12-11dm: Add a simple EEPROM driverSimon Glass
There seem to be a few EEPROM drivers around - perhaps we should have a single standard one? This simple driver is used for sandbox testing, but could be pressed into more active service.
