It did not directly; it called 'fsl_add_bridge' which in turn called 'setup_pci_atmu' I modified the 2.6.28 driver to also call this function. Now the inbound/outbound windows are set up, but the bridge still has no allocations, so the problem remains. I need to move on; I may just live with sliding the PCI space up for now (doesn't really hurt anything, just seems like a hack) -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
