+
+
+Note: this stub is to help with the LEON3 Qemu tutorial.  The following instructions built the image and were run on a Debian Sqeeze host.
+
+Download the latest release of the [http://www.denx.de/wiki/U-Boot/WebHome universal boot loader] from [ftp://ftp.denx.de/pub/u-boot/u-boot-latest.tar.bz2 the ftp] or, you can check out the developer branch using git. 
+ $ git clone git://git.denx.de/u-boot.git
+ $ cd u-boot
+
+Locate the board to build. For example, if you wanted to build u-boot for the leon3...
+ u-boot$ grep -R "leon3"
+
+Set the toolchain
+ $ export CROSS_COMPILE=/opt/rtems-4.11/bin/sparc-rtems4.11-
+Build the package with the following configure command:
+
+  $ /configure --prefix=/tmp/g2/build
+  $ make all install
+
+where the prefix can be anything suitable for your machine. If configure fails with a missing LZO library check you have the lzo-devel package installed.
+
+To make the floppy image follow the instructions in the Grub Wiki at http://grub.enbug.org/TestingOnX86. This script is adapted from the instructions:
+
+ #! /bin/sh -x
+ grub=/tmp/g2/build
+ workspace=/tmp/g2
+ mnt=$workspace/mnt/loop
+ file=$workspace/rtems-boot.img
+ export PATH=$grub/bin:$grub/sbin:$PATH
+ mkdir -p $workspace
+ cd $workspace
+ grub-mkimage -o core.img _chain ls pc multiboot gpt fat boot reboot configfile cat help
+ dd if=/dev/zero of=$file bs=512 count=2880
+ /sbin/mkdosfs $file
+ mkdir -p $mnt
+ mount -o loop -t vfat $file $mnt
+ mkdir -p $mnt/boot/grub
+ cp $grub/lib/grub/i386-pc/boot.img core.img $grub/lib/grub/i386-pc/*.mod $mnt/boot/grub
+ echo "configfile (hd0,0)/rtems-grub.cfg" > $mnt/boot/grub/grub.cfg
+ echo '(fd0)' $file > tmp_device.map
+ grub-setup -d $mnt/boot/grub -r '(fd0)' -m tmp_device.map '(fd0)'
+ rm -f tmp_device.map
+ umount $mnt
