Hello! USB_XHCI_MVEBU has currently "depends on ARCH_MVEBU" which means that USB_XHCI_MVEBU cannot be enabled when ARCH_MVEBU is disabled. So "default y if ARCH_MVEBU" is same as "default y". If you have mvebu board when mvebu xhci controller is unused, you can disable this option and save some space. I see that other xhci drivers have also "default y" so seems that this is the standard default option.
