From 38805e5f096162867a70c7468c654d7f9bb507da Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 10 Jul 2007 23:37:45 -0500 Subject: [POWERPC] Add the ability to find PCI capabilities early on Added early_find_capability that wraps pci_bus_find_capability and uses fake_pci_bus() to allow us to call it before we've fully setup the pci_controller.
