93e502b3c2 MIPS: OCTEON: Platform support for OCTEON III USB controller
Add all the necessary platform code to initialize the dwc3
USB host controller. This code initializes the clocks and
performs a reset on the USB core and PHYs. The driver code
in 'drivers/usb/dwc3' is where the real driver lives.

63a4aea556 of: clean-up unnecessary libfdt include paths
With the libfdt include fixups to use "" instead of <> in the
latest dtc import in commit 4760597 (scripts/dtc: Update to upstream
version 9d3649bd3be245c9), it is no longer necessary to add explicit
include paths to use libfdt. Remove these across the kernel.

f421258d5b MIPS: OCTEON: add crypto helper functions
Add crypto helper functions which are needed for kernel level usage.
The code for these has been extracted from the EdgeRouter Pro GPL tarball.

While at it, also delete duplicate definitions of the functions.

e326479f2f MIPS: Octeon: Move device-trees to arch/mips/boot/dts/
Move the Octeon device-trees to arch/mips/boot/dts/ and update the
Makefiles accordingly.  Since Octeon requires the device-tree to be
built into the kernel, select BUILTIN_DTB as well.

90b335fbbc kbuild: centralize .dts->.dtb rule
All architectures that use cmd_dtc do so in almost the same way. Create
a central build rule to avoid duplication. The one difference is that
most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather
than building the .dtb in the same directory as the .dts file. This
difference will be eliminated arch-by-arch in future patches.

MIPS is the exception here; it already uses the exact same rule as the
new common rule, so the duplicate is removed in this patch to avoid any
conflict. arch/mips changes courtesy of Ralf Baechle.

Update Documentation/kbuild to remove the explicit call to cmd_dtc from
the example, now that the rule exists in a centralized location.

736b1c9c95 MIPS: Octeon: Add device tree source files.
The two device tree files octeon_3xxx.dts and octeon_68xx.dts are
trimmed by code in a subsequent patch to reflect the hardware actually
present on the board.  To this end several properties that are not
part of the declared bindings are added to aid in trimming off
unwanted nodes.  Since the device tree and the code that trims it are
bound into the kernel binary, these 'marker' properties never escape
into the wild, and are purely an implementation detail of the kernel
early boot process.  This is done for backwards compatibility with
existing boards (identified by a board type enumeration value by their
bootloaders).  New boards will always pass a device tree from the
bootloader, the built-in trees are ignored in this case.

These are the rest of the new files needed to add OCTEON processor
support to the Linux kernel.  Other than Makefile and Kconfig which
should be obvious, we have:

csrc-octeon.c   -- Clock source driver for OCTEON.
dma-octeon.c    -- Helper functions for mapping DMA memory.
flash_setup.c   -- Register on-board flash with the MTD subsystem.
octeon-irq.c    -- OCTEON interrupt controller managment.
octeon-memcpy.S -- Optimized memcpy() implementation.
serial.c        -- Register 8250 platform driver and early console.
setup.c         -- Early architecture initialization.
smp.c           -- OCTEON SMP support.
octeon_switch.S -- Scheduler context switch for OCTEON.
c-octeon.c      -- OCTEON cache controller support.
cex-oct.S       -- OCTEON cache exception handler.

asm/mach-cavium-octeon/*.h -- Architecture include files.
