I was looking at the ohci-ppc-of driver that has "ohci-bigendian" compatible string and enables both be-mmio and be-desc for the device in this case. I just wanted to separate mmio and desc stuff for ehci, since some devices need be-mmio only. I'll use "big-endian" property instead of "ehci-be-mmio" compatible value. That's a good point, thanks. Do I have to add "sequoia usb ehci" description to Documentation/powerpc/booting-without-of.txt? Do I also have to describe ehci-ppc-of stuff in general? BTW, I see nothing about ohci-ppc-of there.
