Hi,

This commit seems to cause problems with PCI devices doing DMA, just
with mpc85xx ads. If you do the "fsl_add_bridge()" after you setup the
ppc_md.pci_exclude_device to mpc85xx_exclude_device, then the
early_read_config_word() calls in
arch/powerpc/sysdev/fsl_pci.c:setup_pci_cmd() are like no-ops.
This issue was found by David Beazley (on the CC), he can respond to
more detailed questions on it. The fix he came up with was to remove the
"pci_exclude_device".

OK, please send a patch.
I was hoping Jia Hongtao could address why it wasn't address in the
original patch. Some of the other boards also have an exclude function,
and I wonder if those work with this change.
