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. ;)
