Changes for U-Boot 1.0.0:
======================================================================
+* Fix problems in memory test on some boards (which was not
+ non-destructive as intended)
+
+* Patch by Gary Jennejohn, 28 Oct 2003:
+ Change fs/fat/fat.c to put I/O buffers in BSS instead on the stack
+ to prevent stack overflow on ARM systems
+
* Patch by Stephan Linz, 28 Oct 2003:
fix init sequence error for NIOS port
