- 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.

- Merge the *_SET macros from fire(4) which generally print out the 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.

- Enable DMA write parity error interrupts on Schizo with a working implementation. - Revert the Sun Fire V890 WAR of r205254. Instead let schizo_pci_bus() only panic in case of fatal errors as the interrupt triggered by the error the firmware of these and also Sun Fire 280R with version 7 Schizo caused may happen as late as using the HBA and not only prior to touching the PCI bus (in the former case the actual error still is fatal but we clear it before touching the PCI bus). While at it count and export non-fatal error interrupts via sysctl(9). - Remove unnecessary locking from schizo_ue().

- According to OpenSolaris, CDMA flushing/syncing for Tomatillos and XMITS has to be basically done in the same manner as for the Sabres, i.e. only for devices behind PCI-PCI-bridges and after a PIO read on the far side of the farest PCI-PCI-bridge. Given that the Tomatillo documentation mentions no difference to the Schizo bridges in this regard and this is also still part of the procedure described Schizo documentation this seems about right so adjust accordingly (the unconditional CDMA flushing/syncing previously done was based on how Linux behaves). - Implement CDMA flushing/syncing for Schizo version >= 5, which requires the workaround described in Schizo Errata I-23. According to Schizo Errata I-13 it's just unusable with version < 5 though. [1] - Don't register the Schizo streaming buffer for now until it's usage is sorted out according to the erratas. - Register our interrupt filters with the revived INTR_FAST so they these interrupts can even interrupt filters of device drivers as necessary. - Remove the comment regarding lack of newbus'ified bus_dma(9) as being able to associate a DMA tag with a device would allow to implement CDMA flushing/syncing in bus_dmamap_sync(9) but that would totally kill performance. Given that for devices not behind a PCI-PCI bridge the host-to-PCI bridges also only do CDMA flushing/syncing based on interrupts there's no additional disadvantage for polling(4) callbacks in the case schizo(4) has to do the CDMA flushing/syncing but rather a general problem.

Add a driver for `Schizo' Fireplane/Safari to PCI 2.1 and `Tomatillo' JBus to PCI 2.2 bridges. In theory, this driver should also handle `XMITS' Fireplane/Safari to PCI-X bridges but due to lack of access to such hardware, support for these hasn't be fleshed out, yet.
