Changes since U-Boot 1.1.1:
======================================================================
+* Configure SX1 board to use drivers/cfi_flash.c
+
+* Patches by Michael Bendzick, 30 Aug 2004:
+ - Configure omap1510inn board to use drivers/cfi_flash.c
+ - Make drivers/cfi_flash.c protect environment and redundant
+ environment.
+
+* Patch by Steven Scholz, 23 Jun 2004:
+ - Add script (tools/img2brec.sh) to programm U-Boot into
+ (Synch)Flash using the Bootstrap Mode of the MC9328MX1/L
+
* Patches by Scott McNutt, 24 Aug 2004:
- Add support for Altera Nios-II processors.
- Add support for Psyent PCI-5441 board.

+# containg processor init code, SynchFlash programming code and U-Boot data in
+# form of so called b-records.
+#
+# This can be used to programm U-Boot into (Synch)Flash using the Bootstrap
+# Mode of the MC9328MX1/L
