Changes since U-Boot 1.1.4:
======================================================================
+* Extended README entry on coding style
+
+* Added another example showing simple interrupt interception.
+
+* Added simple_strtoul(), getenv() and setenv() to the exported functions.
+ Also bumped up ABI version to reflect this change.
+
+* Added interrupt handling capabilities for mpc5xxx processors.
+ Also added Linux like BUG() macros.
+
* Coding Style cleanup.
