Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS for 4.5 plus some 4.4 fixes.
The executive summary:
- ATH79 platform improvments, use DT bindings for the ATH79 USB PHY.
- Avoid useless rebuilds for zboot.
- jz4780: Add NEMC, BCH and NAND device tree nodes
- Initial support for the MicroChip's DT platform. As all the device
drivers are missing this is still of limited use.
- Some Loongson3 cleanups.
- The unavoidable whitespace polishing.
- Reduce clock skew when synchronizing the CPU cycle counters on CPU
startup.
- Add MIPS R6 fixes.
- Lots of cleanups across arch/mips as fallout from KVM.
- Lots of minor fixes and changes for IEEE 754-2008 support to the
FPU emulator / fp-assist software.
- Minor Ralink, BCM47xx and bcm963xx platform support improvments.
- Support SMP on BCM63168"

Add dummy.o to the targets list, and fill targets automatically from
$(vmlinuzobjs) to avoid having to maintain two lists.
When building with XZ compression copy ashldi3.c to the build
directory to use a different object file for the kernel and zboot.
Without this the same object file need to be build with different
flags which cause a rebuild at every run.

Add device tree nodes for the NEMC and BCH to the JZ4780 device tree,
and make use of them in the Ci20 device tree to add a node for the
board's NAND.
Note that since the pinctrl driver is not yet upstream, this includes
neither pin configuration nor busy/write-protect GPIO pins for the
NAND. Use of the NAND relies on the boot loader to have left the pins
configured in a usable state, which should be the case when booted
from the NAND.

The regmap API has an endianness setting for formatting reads and writes.
This can be set by the usual DT "little-endian" and "big-endian" properties.
To work properly the associated regmap_bus needs to read/write in native
endian.
The "syscon" DT device binding creates an mmio-based regmap_bus which
performs all reads/writes as little-endian. These values are then converted
again by regmap, which means that all of the MIPS BCM boards (which are
big-endian) have been declared as "little-endian" to get regmap to convert
them back to big-endian.
Modify regmap-mmio to use the native-endian functions __raw_read*() and
__raw_write*() instead of the little-endian functions read*() and
write*().
Modify the big-endian MIPS BCM boards to use what will now be the correct
endianness instead of pretending that the devices are little-endian.

Move memory configuration to be performed via device tree for the Malta
board. This moves more Malta specific code to malta-dtshim.c, leaving
the rest of the mti-malta code a little more board-agnostic. This will
be useful to share more code between boards, with the device tree
providing the board specifics as intended.
Since we can't rely upon Malta boards running a bootloader capable of
handling devictrees & filling in the required information, a piece of
shim code (malta_dt_shim) is added to consume the (e)memsize variables
provided as part of the bootloader environment (or on the kernel command
line) then generate the DT memory node using the provided values.

Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs
are not really dependent on a platform being enabled or any other kernel

that len to 0x01ffffff and decompress fails later.
We could hit this problem with crashkernel booting that uses kexec loading
kernel above 4GiB.
We have decompress_* support:
1. inbuf[]/outbuf[] for kernel preboot.
2. inbuf[]/flush() for initramfs
3. fill()/flush() for initrd.
This bug only affect kernel preboot path that use outbuf[].
Add __decompress and take real out_buf_len for gunzip instead of guessing

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for 4.3 for MIPS. Here's the summary:
Three fixes that didn't make 4.2-stable:
- a -Os build might compile the kernel using the MIPS16 instruction
set but the R2 optimized inline functions in <uapi/asm/swab.h> are
implemented using 32-bit wide instructions which is invalid.
- a build error in pgtable-bits.h for a particular kernel
configuration.
- accessing registers of the CM GCR might have been compiled to use
64 bit accesses but these registers are onl 32 bit wide.
And also a few new bits:
- move the ATH79 GPIO driver to drivers/gpio
- the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
change ATH79 accordingly.
- fix definition of pgprot_writecombine
- add an implementation of dma_map_ops.mmap
- fix alignment of quiet build output for vmlinuz link
- BCM47xx: Use kmemdup rather than duplicating its implementation
- Netlogic: Fix 0x0x prefixes of constants.
- merge Bjorn Helgaas' series to remove most of the weak keywords
from function declarations.
- CP0 and CP1 registers are best considered treated as unsigned
values to avoid large values from becoming negative values.
- improve support for the MIPS GIC timer.
- enable common clock framework for Malta and SEAD3.
- a number of improvments and fixes to dump_tlb().
- document the MIPS TLB dump functionality in Magic SysRq.
- Cavium Octeon CN68XX improvments.
- NetLogic improvments.
- irq: Use access helper irq_data_get_affinity_mask.
- handle MSA unaligned accesses.
- a number of R6-related math-emu fixes.
- support for I6400.
- improvments to MSA support.
- add uprobes support.
- move from deprecated __initcall to arch_initcall.
- remove finish_arch_switch().
- IRQ cleanups by Thomas Gleixner.
- migrate to new 'set-state' interface.
- random small cleanups"

Add support for detecting a vmlinuz.bin appended dtb and overriding
the boot arguments to match the UHI interface.
To ensure _edata / __apendend_dtb points to the actual end of the
binary, align the data section to 16 bytes instead of the address
cursor.
Due to ld.script not going through the preprocessor, we can't check
for MIPS_ZBOOT_APPENDED_DTB being enabled, so always reserve space
for it. It should have no consequences for booting without it enabled
except 1 MiB more ram usage during the uncompressing stage.

very ugly and confusing. Since Loongson-2/3 are both 64-bit general-

Use the generic irqchip_init function to probe irqchip drivers using DT,
and add the appropriate node to the JZ4740 devicetree in place of the
call to mips_cpu_irq_init.

Require a DT for JZ4740 based systems, and add a stub one for the
qi_lb60 (Ben NanoNote) board. Devices will be migrated to being probed
via this DT over time.

!CONFIG_DEBUG_ZBOOT doesn't need puts() and puthex(), remove them and
the corrospindig strings for !CONFIG_DEBUG_ZBOOT, as a result, it saves
about 1280 bytes.
[ralf@linux-mips.org: Resolved reject.]

DSR-1000N board has two GPIO LEDs next to USB ports. Add support for them.
[ralf@linux-mips.org: Resolved conflict due to the moving of the DTS files
into vendor subdirectories.]
