Changes for U-Boot 1.1.4:
======================================================================
+* Fix problem in ppc4xx eth-driver without ethaddr (only without
+ CONFIG_NET_MULTI set)
+ Patch by Stefan Roese, 10 Oct 2005
+
+* Fix gzip bmp support (test if malloc fails, warning when truncated).
+ Increase CFG_VIDEO_LOGO_MAX_SIZE on HH405 board.
+ Patch by Stefan Roese, 07 Oct 2005
+
* Add support for OF flat tree for the STXtc board.
