- Copy stable/10 (r259064) to releng/10.0 as part of the 10.0-RELEASE cycle. - Update __FreeBSD_version [1] - Set branch name to -RC1
[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so start releng/10.0 at '100' so the branch is started with a value ending in zero.

Adapt parts of the sparc64 Open Firmware bus enumeration code (in particular, the code for parsing interrupt maps) to PowerPC and reflect their new MI status by moving them to the shared dev/ofw directory.
This commit also modifies the OFW PCI enumeration procedure on PowerPC to allow the bus to find non-firmware-enumerated devices that Apple likes to add, and adds some useful Open Firmware properties (compat and name) to the pnpinfo string of children on OFW SBus, EBus, PCI, and MacIO links. Because of the change to PCI enumeration on PowerPC, X has started working again on PPC machines with Grackle hostbridges.

- Move the declaration of struct upa_ranges and the UPA_RANGE_* macros from sys/sparc64/include/ofw_upa.h to sys/sparc64/pci/ofw_pci.h and rename them to struct ofw_pci_ranges and OFW_PCI_RANGE_* respectively. This ranges struct only applies to host-PCI bridges but no to other bridges found on UPA. At the same time it applies to all host-PCI bridges regardless of whether the interconnection bus is Fireplane/ Safari, JBus or UPA. - While here rename the PCI_CS_* macros in sys/sparc64/pci/ofw_pci.h to OFW_PCI_CS_* in order to be consistent and change this header to use uintXX_t instead of u_intXX_t.

- Remove the old sparc64 OFW PCI code (as opposed to the former "options OFW_NEWPCI"). This is a bit overdue, the new sparc64 OFW PCI code which is meant to replace the old one is in place for 10 months and enabled by default in GENERIC for 8 months. FreeBSD 5.2 and 5.2.1 also shipped with the new code enabled by default. - Some minor clean-up, e.g. remove functions that encapsulated the #ifdefs for OFW_NEWPCI, remove unused resp. no longer required includes, etc.

Fix the EBus driver to work with the new PCI code. Unlike other PCI bridges, the EBus bridge has resource ranges it claims exclusively to map its children into in its BARs. Hence, we need to allocate these completely and manage them for the children, instead of just passing allocations through to the PCI layer as we did before.
While being there, split ebus_probe(), which did also contain code normally belonging into the attach method, into ebus_probe() and ebus_attach(), and perform some minor cleanups.

Add the new sparc64 OFW PCI framework, conditional on options OFW_NEWPCI for now. It introduces a OFW PCI bus driver and a generic OFW PCI-PCI bridge driver. By utilizing these, the PCI handling is much more elegant now.
The advantages of the new approach are: - Device enumeration should hopefully be more like on Solaris now, so unit numbers should match what's printed on the box more closely. - Real interrupt routing is implemented now, so cardbus bridges etc. have at least a chance to work. - The quirk tables are gone and have been replaced by (hopefully sufficient) heuristics. - Much cleaner code.
There was also a report that previously bogus interrupt assignments are fixed now, which can be attributed to the new heuristics.
A pitfall, and the reason why this is not the default yet, is that it changes device enumeration, as mentioned above, which can make it necessary to change the system configuration if more than one unit of a device type is present (on a system with two hme cars, for example, it is possible that hme0 becomes hme1 and vice versa after enabling the option). Systems with multiple disk controllers may need to be booted into single user (and require manual specification of the root file system on boot) to adjust the fstab. Nevertheless, I would like to encourage users to use this option, so that it can be made the default soon.
In detail, the changes are: - Introduce an OFW PCI bus driver; it inherits most methods from the generic PCI bus driver, but uses the firmware for enumeration, performs additional initialization for devices and firmware-specific interrupt routing. It also implements an OFW-specific method to allow child devices to get their firmware nodes. - Introduce an OFW PCI-PCI bridge driver; again, it inherits most of the generic PCI-PCI bridge driver; it has it's own method for interrupt routing, as well as some sparc64-specific methods (one to get the node again, and one to adjust the bridge bus range, since we need to reenumerate all PCI buses). - Convert the apb driver to the new way of handling things. - Provide a common framework for OFW bridge drivers, used be the two drivers above. - Provide a small common framework for interrupt routing (for all bridge types). - Convert the psycho driver to the new framework; this gets rid of a bunch of old kludges in pci_read_config(), and the whole preinitialization (ofw_pci_init()). - Convert the ISA MD part and the EBus driver to the new way interrupts and nodes are handled. - Introduce types for firmware interrupt properties. - Rename the old sparcbus_if to ofw_pci_if by repo copy (it is only required for PCI), and move it to a more correct location (new support methodsx were also added, and an old one was deprecated). - Fix a bunch of minor bugs, perform some cleanups.
In some cases, I introduced some minor code duplication to keep the new code clean, in hopes that the old code will be unifdef'ed soon.

Make the OpenFirmware interrupt mapping code more generic, to reduce the bus-dependent code and to be able to support more systems. The core of the new code is mostly obtained from NetBSD. Kluge the interrupt routing methods of the psycho and apb drivers so that an intline of 0 can be handled for now; real routing is still not possible (all intline registers are preinitialized instead); this will require a sparc64-specific adaption of the driver for generic PCI-PCI bridges with a custom routing method to work right.
