From d27c08c2898d1d74765a7799628d1c18369fd671 Mon Sep 17 00:00:00 2001 From: Myles Watson Date: Fri, 6 Nov 2009 23:42:26 +0000 Subject: Remove drivers/pci/onboard. The only purpose was for option ROMs, which are now handled more generically using CBFS. Simplify the option ROM code in device/pci_rom.c, since there are only two ways to get a ROM address now (CBFS and the device) and add an exception for qemu.
