Changes for U-Boot 1.1.4:
======================================================================
+* Add support for AMCC 440SP, add support for AMCC Luan 440SP eval board.
+ Patch by John Otken, 23 Nov 2005
+
* Changed PPC44x startup message (cpu info, speed...) to common style:
On PPC44x platforms, the startup message generated in "cpu.c" only
comprised the ppc type and revision but not additional informations
D: Initial support for SSV-DNP1110, SMC91111 driver
