* Take the PHY of iec(4) out of reset before attaching the interface.visa2016-01-022-3/+17
| | | | | | | | | | | | Otherwise the PHY goes undetected on the slave node of a dual-node Origin 200. The PHY gets enabled by diagnostic checks but only on the master node. As the attach code will now do the enabling, the checks can be disabled on reboot, making reboots faster especially on IP27. Tested on Origin 200 (IP27), Fuel (IP35 with iec), and Origin 350 (IP35 without iec). Diff from miod@, ok krw@

| | | | | | | | | | | accessors or the byte-swapped accessors, depending upon the byteswap setting of the device we are trying to attach. This allows for the removal of byteswap knowledge from ioc(4) and iof(4) drivers. While there, build pci_chipset_t md structs by bcopy'ing a template and filling the few runtime fields, instead of assigning every field of them.
* Introduce pci_probe_device_hook(pci_chipset_tag_t, struct pci_attach_args *).miod2011-10-102-8/+27
| | | | | | | | | | | | | | | | | | This mandatory function will get invoked in pci_probe_device(), and allows a pci host driver to alter the pci_attach_args passed to a device when attaching. This function will also, if returning non-zero, cause the device to be skipped completely during all the phases of the PCI device discovery (i.e. ressource enumeration, ressource assignment, and actual attachment). This particular feature is experimental and might be reverted in the future (or the scope narrowed to device attachment only). A dummy #define pci_probe_device_hook() 0 is added to all platforms except sgi, where real functions (currently only returning 0) are added; real meat will be added shortly. Discussed at s2k11, no objection from the usual suspects.

| | | | | | | | | | | | | | | superio chip interrupt on two different pins (yet do not advertize themselves as a multi-function device, of course). So, on one hand, this makes the ioc attachment code simpler, because it simply needs to map interrupt pins A and B, and another hand, this moves all the interrupt knowledge to the PCI bridge driver, since routing of pin B differs whether the device is the onboard IOC3 chip (and able to use any of the 8 bridge interrupt sources...) or on a PCI board (with pin mapping sane, since controlled by the bridge). This makes superio interrupts on CADduo boards work. Tested to cause no regressions on Origin 200, Octane and Fuel.
