Non default Drive Strength cannot be set automatically. It is a function of the board design and only if there is a specific platform handler can it be set. The platform handler needs to take into account the board design. Pass to the platform code the necessary information. For example: The card and host controller may indicate they support HIGH and LOW drive strength. There is no way to know what should be chosen without specific board knowledge. Setting HIGH may lead to reflections and setting LOW may not suffice. There is no mechanism (like ethernet duplex or speed pulses) to determine what should be done automatically. If no platform handler is defined -- use the default value.
