b6ba1c5294 MIPS: PCI: Netlogic XLP9XX support
Add PCI support for Netlogic XLP9XX. The PCI registers and
SoC bus numbers have changed in XLP9XX.

Also skip a few (bus,dev,fn) combinations which have issues when
read.

c24a8a7a99 MIPS: Netlogic: Add MSI support for XLP
Add MSI chip and MSIX chip definitions.

For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.

The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.

For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.

The MSI-X chip definition uses the standard functions to enable
and disable interrupts.

27547abf36 MIPS: malta: Incorporate PIIX4 ACPI I/O region in PCI controller resources
Boot log says:

pci 0000:00:0a.3: no compatible bridge window for [io  0x1000-0x103f]
pci 0000:00:0a.3: no compatible bridge window for [io  0x1100-0x110f]

The io resource starting point on Malta was modified by c5de50dada (MIPS:
Malta: Change start address to avoid conflicts.) to avoid conflicts with
ACPI and SMB devices. In fact, that was not needed (and now causing
southbridge ACPI missing) since 166c637075 (PCI: add pci_create_root_bus()
that accepts resource list) and 7c090e5bfa (mips/PCI: convert to
pci_scan_root_bus() for correct root bus resources) had already done the
correct fix.

This patch actually reverts the change made by c5de50dada. And with this
fix, log says:

pci 0000:00:0a.3: quirk: [io  0x1000-0x103f] claimed by PIIX4 ACPI
pci 0000:00:0a.3: quirk: [io  0x1100-0x110f] claimed by PIIX4 SMB

These things may not be used but as part of platform resources are better
off to be included.

8bb5a87508 MIPS: sead3: remove chosen node
The defaults are not always applicable and it makes it hard for the bootloader
to override them. By removing it we give the bootloader full control over what
command line parameters to pass.

Without this change we will need to modify the built-in dtb to add bootloader
cmd line parameters or do some work to append them after we unflatten the device
tree.

Sead3 is a development board, that's why we want to be able to change boot
parameters on the fly from the bootloader.

23a91de41c MIPS: Malta: use generic 8250 early console
This patch switches Malta from using the MIPS implementation of early
printk with Malta's prom_putchar to using the generic 8250_early
implementation. This offers a couple of advantages:

  - We duplicate less generic code.

  - The UART can be initialised rather than being reliant upon
    inheriting a valid setup from the bootloader.

The Malta console_config function is extended to initialise the early
console if no earlycon= kernel parameter is provided, inheriting the
modetty0 bootloader environment if present and falling back to a
default 38400n8r setup if not. This matches the behaviour used for the
regular console= parameter.

ae0d7cbc99 MIPS: Malta: mux & enable SERIRQ interrupt
This patch causes the kernel to mux the SERIRQ interrupt to the SERIRQ
pin of the PIIX4 and to enable that interrupt. The kernel depends upon
the interrupt when using the SuperIO UARTs (ttyS0 & ttyS1) but
previously would not configure it, instead relying upon the bootloader
having done so. If that is not the case then the typical result is that
the system appears to hang once it reaches userland as no output is
displayed on the UART.

b2e4f1560f MIPS: cavium-octeon: fix early boot hang on EBH5600 board
The boot hangs early on EBH5600 board when octeon_fdt_pip_iface() is
trying enumerate a non-existant interface. The actual hang happens in
cvmx_helper_interface_get_mode():

	mode.u64 = cvmx_read_csr(CVMX_GMXX_INF_MODE(interface));

when interface == 4. We can avoid this situation by first checking that
the interface exists in the DTB.

8b75e77048 MIPS: cavium-octeon: fix out-of-bounds array access
When booting with in-kernel DTBs, the pruning code will enumerate
interfaces 0-4. However, there is memory reserved only for 4 so some
other data will get overwritten by cvmx_helper_interface_enumerate().

885014bcf2 MIPS: improve checks for noncoherent DMA
Only one MIPS development board actually supports enabling/disabling DMA
coherency at runtime, so it's not a good idea to push the overhead of
checking that configuration setting onto every other supported target as
well.
