Use the tarball and patch in the 'shoehorn-2' directory to boot the
2.2.1 kernel on the EDB7211.

Use the shoehorn versions in the 'shoehorn-3-obsolete' directory to boot
the 2.4.0-test kernels.  These versions don't use the final EDB7211 kernel
architecture number, and we changed numbers once in this series; make sure
your shoehorn architecture number matches your kernel architecture number.

To find out the architecture number in shoehorn, look for the put_word()
calls at the end of shoehorn.c; for the kernel, look in arm/arm/tools/
mach-types.

Use shoehorn-3.4.tar.gz or later if you're using the released 2.4.0
kernel or later.  This version uses the final architecture number for
the EDB7211 (which is 50).
