Cover letter [Qemu-devel] [PATCH v4 0/7] prep: improve Raven PCI host emulation
This patchset improves Raven PCI host emulation, found in some PPC platforms, like the QEMU 'prep' one, and for example the IBM RS/6000 40p.
Some features added to raven emulation were already present in prep board (non contiguous I/O, firmware loading), while some other are new (PCI bus mastering memory region).
This patchset has been tested against Linux 2.4 PPC and IBM RS/6000 40p firmware.
Notable achievements are PCI bus mastering (tested with lsi53c895a SCSI adapter), lots of cleanup and emulation correctness, and also documentation of current hacks required by Open Hack'Ware.
This gives us a good base to replace OpenHack'Ware by a possible upcoming OpenBIOS release.
Changes since v3:
- rebased and removed patches already applied
- moved non contiguous I/O patch sooner, to not break bisectability
Changes since v2:
- rebased and fixed conflicts in patches 5 and 6
Changes since v1:
- reworked a dubious memcpy to make it work on big endian hosts
- split onto multiple patches
Hervé Poussineau (7):
raven: rename intack region to pci_intack
raven: implement non-contiguous I/O region
raven: set a correct PCI I/O memory region
raven: set a correct PCI memory region
raven: add PCI bus mastering address space
raven: fix PCI bus accesses with size > 1
raven: use raven_ for all function prefixes
