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 documentati= on 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 Herv=C3=A9 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 hw/pci-host/prep.c | 180 ++++++++++++++++++++++++++++++++++++++++++----= ------ hw/ppc/prep.c | 103 ++++-------------------------- 2 files changed, 159 insertions(+), 124 deletions(-) --=20 1.7.10.4
