 > I will disable index port but I find the OFW can't flash EC or OFW when
 I disable index port.
 > Whether the *flash* command use the 38x port or not, can you check?

 David:

 Please don't disable the Indexed IO in the EC.  We decided it will be much
 better to just let Openfirmware decide when to disable this.  It is a very
 useful debugging tool.  On production roms we will disable the Indexed IO
 right before write protecting the SPI flash.
