When loading a Freescale 2.6.35 on a mx28evk the following issue is seen:

sgtl5000_hw_read: read reg error : Reg 0x00
Device with ID register 0 is not a SGTL5000

Disabling CONFIG_CMD_I2C makes the sgtl5000 probe to succeed.

Mainline kernel does not show this problem.

Until the real cause is not identified, disable 'CONFIG_CMD_I2C' for the 
time being.

Stefano,

Since 2013.04 is approaching I prefer to disable this option until the real
cause is identified.
