I2C Issue #59

I'm having issues reading the EEPROM chip via I2C on a Olimex A10-OLinuXino-LIME.

After some trial and error, I was able to access the EEPROM like this in linux:

# i2cget 1 0x50 0x0
# i2cget 1 0x50 0x0
  => 0x11

However I can't seem to access it via the i2c command in U-Boot:

# i2c md 0 0x50 0x0
Error reading the chip.
# i2c md 1 0x50 0x0
Error reading the chip.

Looking at the source, i2c probe was never implemented in the driver, so I can't see anything there either.

Unfortunately I'm not well versed in C and this is my first attempt in to embedded systems, so I'm still not completely sure what I'm doing...

Is this a bug or can someone point me in the right direction? Thanks!
