Great!

Thanks a lot for searching and finding that.

I've just tested an u-boot for the BeagleBoard with your "Move 
DECLARE..."-patch compiled with gcc 4.5.1 and it now boots. ;)

I remember having seen those two DECLARE_GLOBAL_DATA_PTR in beagle.c 
too, but I was to lazy at that time to check if that has (bad) 
consequences. ;)

Regards,

Alexander
