From ff3e077bd23c37c83d01aad105e528194e33d75e Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 5 Mar 2015 12:25:25 -0700 Subject: dm: pci: Add a uclass for PCI Add a uclass for PCI controllers and a generic one for PCI devices. Adjust the 'pci' command and the existing PCI support to work with this new uclass. Keep most of the compatibility code in a separate file so that it can be removed one day.
