Too bad. Thanks for testing though.
Adam & Victor, any ideas? If you don't see a "quick" solution, please provide a temporary fix for this problem.
Markus, the only quick solution that we have for immediate application is to disable the DDR autocalibration and therefore run with the original Kilauea SDRAM static values. This will require you to recompile U-Boot and download it onto your board.
To disable the DDR autocalibration code, in the include/configs/kilauea.h file, undef the "CONFIG_PPC4xx_DDR_AUTOCALIBRATION" definition and recompile U-Boot.
I just sent a patch disabling the autocalibration to the list. I intend to push this to Wolfgang soon. We can enable the autocalibration again when the issue is fixed.
Best regards, Stefan
