From 76bbb00288e569e7bd9ec18f45e4f814352260dd Mon Sep 17 00:00:00 2001 From: Deepak Saxena Date: Sun, 30 Apr 2006 15:34:29 +0100 Subject: [PATCH] [ARM] 3487/1: IXP4xx: Support non-PCI systems Patch from Deepak Saxena This patch allows for the addition of IXP4xx systems that do not make use of the PCI interface by moving the CONFIG_PCI symbol selection to be platform-specific instead of for all of IXP4xx. If at least one machine with PCI support is built, the PCI code will be compiled in, but when building !PCI, this will drastically shrink the kernel size.
