Changes for U-Boot 1.1.3:
======================================================================
+* Add support for ext2 filesystems and image timestamps to TQM5200 board
+
+* Add reset code for Coral-P on INKA4x0 board
+
+* Patch by Martin Krause, 28 Jun 2004:
+ Update for TRAB board.
+
+* Fix some missing "volatile"s in MPC5xxx FEC driver
+
* Fix cirrus voltage detection (for CPC45)
* Fix byteorder problem in usbboot and scsiboot commands.
