+/*
+ * How to use the onboard device driver for option rom execution:
+ *
+ * 1. You need to add the driver to your mainboard Config.lb:
+ *
+ * chip drivers/pci/onboard
+ * device pci x.0 on end
+ * register "rom_address" = "0xfff80000"
+ * end
+ * 2. Reduce the size of your normal (or fallback) image, by adding the
+ * following lines to your target Config.lb, after romimage "normal"
+ * # 48K for SCSI FW or ATI ROM
+ * option CONFIG_ROM_SIZE = 512*1024-48*1024
+ * 3. Create your vgabios.bin, for example using awardeco and put it in the
+ * directory of your target Config.lb. You can also read an option rom from
+ * a running system, but this is unreliable, as some option roms are changed
+ * during execution:
+ * # dd if=/dev/mem of=atix.rom skip=1536 count=96
+ * 4. After you built coreboot.rom, attach the option rom to your coreboot
+ * image:
+ * # cat ../atix.rom ./normal/coreboot.rom ./fallback/coreboot.rom > coreboot.rom
+ *
+ * Alternatively you can use the following script "nsxv" to build your image
+ * Usage:
+ * # ./nsxv s2850
+ *
+ * #!/bin/bash
+ * MBVENDOR=tyan
+ * MBMODEL=$1
+ * LBROOT=/home/yhlu/xx/xx
+ *
+ * echo $1
+ * date
+ *
+ * cd "$LBROOT/freebios2/targets"
+ * rm -rf "$MBVENDOR/$MBMODEL/$MBMODEL"
+ * ./buildtarget "$MBVENDOR/$MBMODEL" &> "$LBROOT/x_b.txt"
+ * cd "$MBVENDOR/$MBMODEL/$MBMODEL"
+ * #make clean
+ * eval make &> "$LBROOT/x_m.txt"
+ * if [ $? -eq 0 ]; then
+ * echo "ok."
+ * else
+ * echo "FAILED! Log excerpt:"
+ * tail -n 15 "$LBROOT/x_m.txt"
+ * exit
+ * fi
+ * cat ../atix.rom ./normal/coreboot.rom ./fallback/coreboot.rom > "$LBROOT/rom/"$MBMODEL"_coreboot.rom"
+ * cp -f "$LBROOT/rom/"$MBMODEL"_coreboot.rom" /home/yhlu/
