powerpc: Add skeleton PowerNV platform This adds a skeletton for the new Power "Non Virtualized" platform which will be used by machines supporting running without an hypervisor, for example in order to run KVM. These machines will be using a new firmware called OPAL for which the support will be provided by later patches. The PowerNV platform is intended to be also usable under the BML environment used internally for early CPU bringup which is why the code also supports using RTAS instead of OPAL in various places.

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>

powerpc/powernv: Improve kexec reliability We add a machine_shutdown hook that frees the OPAL interrupts (so they get masked at the source and don't fire while kexec'ing) and which triggers an IODA reset on all the PCIe host bridges which will have the effect of blocking all DMAs and subsequent PCIs interrupts.
