From 3d137310245e4cdc3e8c8ba1bea2e145a87ae8e3 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 19 Aug 2008 10:28:24 +0200 Subject: PCI: allow quirks to be compiled out This patch adds the CONFIG_PCI_QUIRKS option which allows to remove all the PCI quirks, which are not necessarily used on embedded systems when PCI is working properly. As this is a size-reduction option, it depends on CONFIG_EMBEDDED. It allows to save almost 12 kilobytes of kernel code: text data bss dec hex filename 1287806 123596 212992 1624394 18c94a vmlinux.old 1275854 123596 212992 1612442 189a9a vmlinux -11952 0 0 -11952 -2EB0 +/- This patch has originally been written by Zwane Mwaikambo and is part of the Linux Tiny project.
