-Subject: [PATCH] PCI: iproc: Allow multiple devices except on PAXC
-
-Commit 943ebae781f5 ("PCI: iproc: Add PAXC interface support") only allowed
-device 0, which is a regression on BCMA-based platforms.
-
-All systems support only one device, a Root Port at 00:00.0, on the root
-bus.  PAXC-based systems support only the Root Port (00:00.0) and a single
-device (with multiple functions) below it, e.g., 01:00.0, 01:00.1, etc.
-Non-PAXC systems support arbitrary devices below the Root Port.

-[bhelgaas: changelog, fold in removal of MAX_NUM_PAXC_PF check]
