-//06063001-joelin disable the PCI CFRAME mask -start
-/*CFRAME is an I/O signal, in the chip, the output CFRAME is selected via GPIO altsel pins, so if you select MII1 RXD1, the CFRAME will not come out.
-But the CFRAME input still take the signal from the pad and not disabled when altsel choose other function. So when MII1_RXD1 is low from other device, the EBU interface will be disabled.
-
-The chip function in such a way that disable the CFRAME mask mean EBU not longer check CFRAME to be the device using the bus.
-The side effect is the entire PCI block will see CFRAME low all the time meaning PCI cannot use the bus at all so no more PCI function.
