Dear Michael Schwingen,

The system hangs during early init, and does not get past relocation.
That is to be expected when you use this before relocation. Don't do that, then.
If I interpret the code correct, the PCI code is called from board_init_r on PowerPC platforms.
So what? board_init_r() is (quoting the comment) "the next part if the initialization sequence: we are now running from RAM and have a "normal" C environment, i. e. global data can be written, BSS has been cleared, the stack size in not that critical any more, etc."
So it's perfectly safe and clean to run pci_init() there.
I know - I only wanted to point at the differences: the problem is that the ARM code does it before relocation currently, and I was trying to understand why.
