Check the value of register(0xD000E014) to decide whether this is 50MHZ or 66MHZ board attached. Configure register PHY_CTRL to support 50MHZ or 66MHZ. Default Configure of PHY_CTRL is the configure of 50MHZ, if 66MHZ board attached, change the value of PHY_CTRL.
Excellent shows exactly why we want to use ACPI, let the kernel be generic.
