James Hogan d3087c03f0 metag: *.dts: include using preprocessor
Include *.dtsi files from *.dts using the preprocessor to set a good
example for future device tree files. Files included in the old way
don't get pre-processed.

James Hogan 6ad59a58b0 metag: add <dt-bindings/> symlink
Add symlink to include/dt-bindings from arch/metag/boot/dts/include/ to
match the one in arch/arm/... (see the commit below) so that
preprocessed device tree files can include various useful constant
definitions.

Commit c58299aa87 ("kbuild: create an
"include chroot" for DT bindings") merged in v3.10-rc1.

James Hogan c24d2976c7 metag: minimal TZ1090 (Comet) SoC infrastructure
Add really minimal support for Toumaz Xenif TZ1090 SoC (A.K.A. Comet).
This consists of minimal build infrastructure, device tree files, and a
defconfig based on meta2_defconfig.

This SoC contains a 2-threaded HTP (Meta 2) as the main application
processor, and is found in a number of development boards and digital
radios, such as the Minimorph Development Platform.

James Hogan 0b4184c26b metag: avoid unnecessary builtin dtb rebuilds
The builtin .dtb.S intermediate file needs to be marked with .SECONDARY
so that it isn't automatically deleted (which causes it to be
regenerated on every build). Also add *.dtb.S to clean-files so it gets
cleaned up by make clean.

Similarly, if the specified builtin dtb isn't already in dtb-y (e.g.
imported into the tree and specified in CONFIG_METAG_BUILTIN_DTB_NAME)
it too will be treated as an intermediate and deleted automatically
(again causing it to be regenerated on every build), so add it to dtb-y
so it gets added to targets and the dtbs target.

James Hogan 85d9d7a920 metag: Boot
Add boot code for metag. Due to the multi-threaded nature of Meta it is
not uncommon for an RTOS or bare metal application to be started on
other hardware threads by the bootloader. Since there is a single MMU
switch which affects all threads, the MMU is traditionally configured by
the bootloader prior to starting Linux. The bootloader passes a
structure to Linux which among other things contains information about
memory regions which have been mapped. Linux then assumes control of the
local heap memory region.

A kernel arguments string pointer or a flattened device tree pointer can
be provided in the third argument.
