Changes since U-Boot 1.1.1:
======================================================================
+* Patches by Lars Munch, 12 Jul 2004:
+ - move at45.c to board/at91rm9200dk/ since this is at91rm9200dk
+ board specific
+ - split out the LXT971A PHY from ns_9750_eth.h
+ - split the dm9161 phy part out of at91rm9200_ether.c
+
* Patch by Andreas Engel, 12 Jul 2004:
Replaced hardcoded PL011 clock frequency with config variable.
Fixed wrong CONFIG_CMD_DFL doc.
