From c23bfc3835173f5229b2503e3b616001a28affad Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 10 Mar 2012 12:49:16 +0000 Subject: ARM: PCI: provide a default bus scan implementation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Most PCI implementations perform simple root bus scanning. Rather than having each group of platforms provide a duplicated bus scan function, provide the PCI configuration ops structure via the hw_pci structure, and call the root bus scanning function from core ARM PCI code.
