CONFIG_MXC_USB_PORT was used to define which USB port was to be initialized.

None of the other USB ports would be available for use.
The fix is to remove all instances of CONFIG_MXC_USB_PORT from the imx53 ehci driver since it was only allowing the port specified by CONFIG_MXC_USB_PORT to be populated. Then use CONFIG_USB_MAX_CONTROLLER_COUNT to specifiy which USB ports should be enabled, starting with port 0. If port 1 is needed, then set CONFIG_USB_MAX_CONTROLLER_COUNT to 2 so 2 ports get populated (port 0 and port 1) even though port 0 will not be used.
Configurations for all boards affected are updated.

Hi! Why don't you just define a list of controllers which should be initialized instead ?
#define CONTROLLERS_TO_INIT { USB1, USB3 }
Where USB1 and USB3 is the address of the controller. Note that these addresses are defined in arch/arm/include/ headers.
