The of_node field of the device assigned to a
PCI bus is used during scanning of the PCI bus.
However on MIPS, the of_node field is assigned
only after the bus has been scanned.Implement the architecture specific version of
'pcibios_get_phb_of_node'. Which ensures that the
PCI driver core will initialize the of_node field
before starting the scan.Also remove the local assignment of bus->dev.of_node,
it is not needed after the patch.Signed-off-by: Gabor Juhos

Commit 7517de348663b08a808aff44b5300e817157a568 ("MIPS: Alchemy: Redo
PCI as platform driver") added a reference to CONFIG_DEBUG_PCI. Change
it to CONFIG_PCI_DEBUG, as that is a valid Kconfig macro.Also add a newline to a debugging printk that this fix enables.

Pull MIPS updates from Ralf Baechle:
o Add basic support for the Mediatek/Ralink Wireless SoC family.
o The Qualcomm Atheros platform is extended by support for the new
QCA955X SoC series as well as a bunch of patches that get the code
ready for OF support.o Lantiq and BCM47XX platform have a few improvements and bug fixes.
o MIPS has sent a few patches that get the kernel ready for the
upcoming microMIPS support.o The rest of the series is made up of small bug fixes and cleanups
that relate to various parts of the MIPS code. The biggy in there is
a whitespace cleanup. After I was sent another set of whitespace
cleanup patches I decided it was the time to clean the whitespace
"issues" for once and and that touches many files below arch/mips/.Fix up silly conflicts, mostly due to whitespace cleanups.

Drivers for EDAC on Cavium. Supported subsystems are:
o CPU primary caches. These are parity protected only, so only error
reporting.
o Second level cache - ECC protected, provides SECDED.
o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will
will only initialize if ECC is enabled on a system so is safe to run on
non-ECC memory.
o PCI: Parity error reportingSince it is very hard to test this sort of code the implementation is very
conservative and uses polling where possible for now.Signed-off-by: Ralf Baechle
