This supports SMP Linux running on the BCM3384 Zephyr (BMIPS5000)
application processor, with fully functional UART and USB 1.1/2.0.
Device Tree is used to configure the following items:
- All peripherals
- Early console base address
- SMP or UP mode
- MIPS counter frequency
- Memory size / regions
- DMA offset
- Kernel command line
The DT-enabled bootloader and build instructions are posted at

Move the Ralink device-trees to arch/mips/boot/dts/ and update the
Makefiles accordingly. A built-in device-tree is optional, so select
BUILTIN_DTB when it is requested.

Move the SEAD-3 device-tree to arch/mips/boot/dts/ and update the

Move the Lantiq device-trees to arch/mips/boot/dts/ and update the

device-tree (EASY50712), and it's required to be built into the kernel,
so select BUILTIN_DTB for it.

Add a 'dtbs' Makefile target that just builds the device-tree binaries

In preparation for moving the device-trees to a common location,
introduce the config option BUILTIN_DTB, which can be selected by
platforms that use a device-tree built into the kernel image, and
create a Makefile to build the device-trees in arch/mips/boot/dts/.

Commit 3b29aa5ba204c [MIPS: add <dt-bindings/> symlink] created a symlink
file in include/dt-bindings. Even though commit diff is fine, the symlink
is invalid and ls -lb shows a newline character at the end of the filename:
lrwxrwxrwx 1 maddy maddy 35 Sep 19 18:11 dt-bindings ->

Add symlink to include/dt-bindings from arch/mips/boot/dts/include/ to
match the ones in ARM and Meta architectures so that preprocessed device
tree files can include various useful constant definitions.
See commit c58299a (kbuild: create an "include chroot" for DT bindings)
merged in v3.10-rc1 for details.
MIPS structures it's dts files a little differently to other
architectures, having a separate dts directory for each SoC/platform,
but most of the definitions in the dt-bindings/ directory are common so
for now lets just have a single "include chroot" for all MIPS platforms.
