1016	  system which doesn't have this device will result in long
1017	  delays when I2C/SMBus chip drivers are loaded (e.g. at boot
1018	  time).  If unsure, say N.

1030	  If you say yes here you get an I2C bus that will tunnel i2c commands
1031	  through to the other side of the ChromeOS EC to the i2c bus
1032	  connected there. This will work whatever the interface used to
1033	  talk to the EC (SPI, I2C or LPC).
