metag: *.dts: include using preprocessor

2013-06-27T12:49:43+00:00

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.

metag: add symlink

2013-06-27T12:49:06+00:00

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 c58299aa87544a590c62bda0bf52b69fa56cb8d5 ("kbuild: create an
"include chroot" for DT bindings") merged in v3.10-rc1.

metag: minimal TZ1090 (Comet) SoC infrastructure

2013-06-13T11:14:07+00:00

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.

metag: avoid unnecessary builtin dtb rebuilds

2013-04-22T10:23:20+00:00

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.

metag: Boot

2013-03-02T20:09:17+00:00

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.
