This patch does not fix the problem, during boot the kernel still
panics. I had a closer look at the commit and the following patch
fixes it for me....
diff --git a/arch/powerpc/sysdev/fsl_pci.c

}
The only difference here is that you're not setting hose->ops to
fsl_indirect_pci_ops. Do you know why that is helping, and what
hose->ops is set to instead?
