From 3c8ae536ec26ffc7715e38876b43f88286a98fd8 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 2 Feb 2015 22:35:25 +0800 Subject: [PATCH] x86: Define macros for pci configuration space access Move PCI_REG_ADDR and PCI_REG_DATA from arch/x86/lib/pci_type1.c to arch/x86/include/asm/pci.h, also define PCI_CFG_EN so that these macros can be used for pci configuration space access.
