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
