USB_OHCI_LITTLE_ENDIAN doesn't exactly mean to include support for little-endian controllers; it means include mixed-endian support if either USB_OHCI_BIG_ENDIAN_DESC or USB_OHCI_BIG_ENDIAN_MMIO is set. That is, the driver determines at runtime whether a particular controller is big-endian or little-endian, rather than choosing to support one or the other at compile time. In any case, the style we have adopted is that these select lines go in the arch-specific defconfig, not here. For example, check out the occurrences of EHCI in arch/mips/Kconfig. Also, I'm not sure how you came up with that list of architectures for the two selects; it's hard to say if they are right. For instance, why did you include AVR32? The changes to the driver itself look fine. Similar comments apply to the ehci-platform patch.
