I'm working on a 64-bit MVEBU board which I'll hopefully be submitting
soon (just getting the Linux stuff sorted first). Was there any
particular reason you added the !ARM64 ? My board appears to need
CONFIG_USB_EHCI_IS_TDI=y. I can make the condition more complicated if
necessary but it might just be easier to remove the !ARM64.

Here I'm thinking about something like if !ARM64 || ALLEYCAT_5
