From 53eed4ec8bcd8701b9135859ec46b10a0d88ba25 Mon Sep 17 00:00:00 2001 From: David Vrabel Date: Fri, 9 Sep 2005 13:04:32 -0700 Subject: [PATCH] fbdev: geode updates Geode framebuffer driver updates: - Local mode list (taken from modedb.c) containing only relevant modes. This also makes the driver work as a module. - Make it a PCI driver (from James Simmons ). - A few other minor cosmetic bits and pieces.
