Ralf Baechle 7034228792 MIPS: Whitespace cleanup.
Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

Jayachandran C ea49b750d4 MIPS: PCI: Update XLR/XLS PCI for the new PIC code
Use the nlm_set_pic_extra_ack() call to setup the extra interrupt
ACK needed by XLR PCI and XLS PCIe. Simplify the code by adding
nlm_pci_link_to_irq().

Jayachandran C 4d9bb75823 MIPS: Netlogic: Remove unused pcibios_fixups
This global is unneeded, and seems to be carried over from ancient
code.

Ganesan Ramalingam 249e2a38fb MIPS: Netlogic: MSI enable fix for XLS
MSI interrupts do not work on XLS after commit a776c49
( "PCI: msi: Disable msi interrupts when we initialize a pci device" )
because the change disables MSI interrupts on the XLS PCIe bridges
during the PCI enumeration.

Fix this by enabling MSI interrupts on the bridge in the
arch_setup_msi_irq() function. A new function xls_get_pcie_link()
has been introduced to get the PCI device corresponding to the
top level PCIe bridge on which MSI has to be enabled.

Also, update get_irq_vector() to use the new xls_get_pcie_link()
function and PCI_SLOT() macro for determining the IRQ of PCI devices.

Bjorn Helgaas 2909060699 mips/PCI: replace pci_probe_only with pci_flags
Some architectures (alpha, mips, powerpc) have an arch-specific
"pci_probe_only" flag.  Others use PCI_PROBE_ONLY in pci_flags for
the same purpose.  This moves mips to the pci_flags approach so
generic code can use the same test across all architectures.

Jayachandran C 0c9654072a MIPS: Netlogic: Move code common with XLP to common/
- Move code that can be shared with XLP (irq.c, smp.c, time.c and
  xlr_console.c) to arch/mips/netlogic/common
- Add asm/netlogic/haldefs.h and asm/netlogic/common.h for common and
  io functions shared with XLP
- remove type 'nlm_reg_t *' and use uint64_t for mmio offsets
- Move XLR specific code in smp.c to xlr/wakeup.c
- Move XLR specific PCI code from irq.c to mips/pci/pci-xlr.c
- Provide API for pic functions called from common/irq.c

Jayachandran C 9b130f8004 MIPS: XLR, XLS: Add PCI support.
Adds pci/pci-xlr.c to support for XLR PCI/PCI-X interface and XLS PCIe
interface.
Update irq.c to ack PCI interrupts, use irq handler data to do the
PCI/PCIe bus ack.
