Hi Leif,
Thanks for your remarks.

What do these hardcoded array sizes signify? What makes 4 guaranteed future-proof?
Well, 4 is biggest available for all variants of Armada 7k and 8k. I have no idea for future plans, but would you like to go with some bigger, arbitrarily chosen number (like 8)?.

Is XHCI "storage"?
Well, the devices attached to XHCI controller can be called storage. I thought such name would be more meaningful than PCI_EMULATION whatsoever. Do you wish some other particular name here?
+STATIC MVHW_STORAGE_DESC mA7k8kStorageDescTemplate = {\
- 4, /* XHCI */\
- { 0xF2500000, 0xF2510000, 0xF4500000, 0xF4510000 },\
These addresses would be a lot nicer as #defines.
Ok. Could be in the same header?
