PS3, Line 45: /* Enable_acpimmio_decode_pm04 to enable the ACPIMMIO decode which is needed to access
            : 	   the GPIO registers required for eSPI setup. */
the eSPI setup isn't the only thing that needs this, but i find that the comment suggest that this is only or at least primarily for the eSPI GPIO setup
