register changes when compiled with SCHIZO_DEBUG and take advantage of them. - Add support for the XMITS Fireplane/Safari to PCI-X bridges. I tought I'd need this for a Sun Fire 3800, which then turned out to not being equipped with such a bridge though. The support for these should be complete but given that it hasn't actually been tested probing is disabled for now. This required a way to alter the XMITS configuration in case a PCI-X device is found further down the device tree so the sparc64 specific ofw_pci kobj was revived with a ofw_pci_setup_device method, which is called by the ofw_pcibus code for every device added. - A closer inspection of the OpenSolaris code indicates that consistent DMA flushing/syncing as well as the block store workaround should be applied with every BUS_DMASYNC_POSTREAD instead of in a wrapper around interrupt handlers for devices behind PCI-PCI bridges only as suggested by the documentation (code for the latter actually exists in OpenSolaris but is disabled by default), which also makes more sense. - Add a workaround for Casinni/Skyhawk combinations. Chances are that this solves the crashes seen when using the the on-board Casinni NICs of Sun Fire V480 equipped with centerplanes other than 501-6780 or 501-6790. This also takes advantage of the ofw_pci_setup_device method. - Mark some unused parameters as such.
