From a80a61049b4851fa559ed1562f64e6ef93f6aa55 Mon Sep 17 00:00:00 2001
From: Myles Watson <mylesgw@gmail.com>
Date: Fri, 17 Apr 2009 13:43:46 +0000
Subject: This patch allows you to add lines of the form

pci_rom PATH vendor_id = # device_id = #

to Config.lb files.  No more changing the ROM_SIZE to add an option ROM, and no more manual prepending.

Examples:

pci_rom ../ragexl.rom vendor_id = 0x1002 device_id = 0x4752
pci_rom ../nic.rom vendor_id = 0x1100 device_id = 0x4152
