From: Jacob Pan Date: Mon, 8 Dec 2008 17:44:16 +0000 (-0800) Subject: PCI: avoid early PCI mmconfig init if pci=noearly is given in cmdline X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=23a36002742bca87510201770a7d931c4aa63e97;p=openwrt%2Fstaging%2Fblogic.git PCI: avoid early PCI mmconfig init if pci=noearly is given in cmdline Early type 1 accesses can cause problems on some platforms, and pci=noearly is supposed to prevent them from occurring. However, early mcfg probing code uses type 1 and isn't protected by a check for noearly. This patch fixes that problem.
