From 27b207fd0a0941b03f27e2a82c0468b1a090c745 Mon Sep 17 00:00:00 2001
From: wdenk <wdenk>
Date: Thu, 24 Jul 2003 23:38:38 +0000
Subject: * Implement new mechanism to export U-Boot's functions to standalone 
  applications: instead of using (PPC-specific) system calls we now   use a
 jump table; please see doc/README.standalone for details

* Patch by Dave Westwood, 24 Jul 2003:
  added support for Unity OS (a proprietary OS)
