Nice!

You're probably not using the latest mvebu/pcie branch from jcooper. In
his branch, I see:

+       if (of_pci_range_parser_init(&parser, np))
+               return -EINVAL;

Which should do the right thing.

Could you check that you're running on top of the latest
jcooper/mvebu/pcie branch? Thanks!

You should probably resend your patch with a proper description. Your
description now includes a lot information about unrelated things (the
Armada 370 board you're working on, the build failure you had, etc.).

Best regards,

Thomas
