powerpc/powernv: PCI support for p7IOC under OPAL v2 This adds support for p7IOC (and possibly other IODA v1 IO Hubs) using OPAL v2 interfaces. We completely take over resource assignment and assign them using an algorithm that hands out device BARs in a way that makes them fit in individual segments of the M32 window of the bridge, which enables us to assign individual PEs to devices and functions. The current implementation gives out a PE per functions on PCIe, and a PE for the entire bridge for PCIe to PCI-X bridges. This can be adjusted / fine tuned later. We also setup DMA resources (32-bit only for now) and MSIs (both 32-bit and 64-bit MSI are supported). The DMA allocation tries to divide the available 256M segments of the 32-bit DMA address space "fairly" among PEs. This is done using a "weight" heuristic which assigns less value to things like OHCI USB controllers than, for example SCSI RAID controllers. This algorithm will probably want some fine tuning for specific devices or device types. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

powerpc/powernv: Fixup p7ioc PCIe root complex class code It advertises "host bridge" instead of "PCI to PCI bridge" which confuses the Linux probe code. Signed-off-by: Benjamin

powerpc/powernv: Handle PCI-X/PCIe reset delay The firmware doesn't wait after lifting the PCI reset. However it does timestamp it in the device tree. We use that to ensure we wait long
powerpc/powernv: Handle PCI-X/PCIe reset delay The firmware doesn't wait after lifting the PCI reset. However it does timestamp it in the device tree. We use that to ensure we wait long enough (3s is our current arbitrary setting) from that timestamp to actually probing the bus. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

powerpc/powernv: Add support for p5ioc2 PCI-X and PCIe This adds support for PCI-X and PCIe on the p5ioc2 IO hub using OPAL. This includes allocating & setting up TCE tables and config space access routines. This also supports fallbacks via RTAS when OPAL is absent, using legacy TCE format pre-allocated via the device-tree (BML style) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
