2013-06-27metag: *.dts: include using preprocessorJames Hogan3-3/+3
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.

2013-06-27metag: add <dt-bindings/> symlinkJames Hogan1-0/+1
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.

2013-06-13metag: minimal TZ1090 (Comet) SoC infrastructureJames Hogan3-0/+41
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.

2013-04-22metag: avoid unnecessary builtin dtb rebuildsJames Hogan1-3/+7
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.

2013-03-02metag: BootJames Hogan1-0/+4
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. Signed-off-by: James Hogan <james.hogan@imgtec.com>
