linux-stable.git/arch/xtensa/boot, branch v3.9 Linux kernel stable tree xtensa: use new common dtc rule 2013-02-24T03:12:52+00:00 Stephen Warren swarren@nvidia.com 2013-01-02T18:27:14+00:00 2a02bc166dd1c7dae71bd3115fb10ec0c351a31f The current rules have the .dtb files build in a different directory from the .dts files. This patch changes xtensa to use the generic dtb rule which builds .dtb files in the same directory as the source .dts. This requires moving parts of arch/xtensa/boot/Makefile into newly created arch/xtensa/boot/dts/Makefile, and updating arch/xtensa/Makefile to call the new Makefile.

xtensa: add device trees support 2012-12-19T05:10:23+00:00 Max Filippov jcmvbkbc@gmail.com 2012-11-03T20:30:13+00:00 da844a81779e2bb263eca4ecb1046541fdb11cf8 Device trees allow specification of hardware topology and device parameters at runtime instead of hard-coding them in platform setup code. This allows running single binary kernel on a range of compatible boards. New boot parameters tag BP_TAG_FDT is allocated and a pointer to flat device tree is passed in it. Note that current interrupt mapping scheme uses single cell for interrupt identification. That means that IRQ numbers used in DTS must be CPU internal IRQ numbers, not external. It is possible to extend interrupt identification to two cells, and use second cell to tell external IRQ numbers form internal. That would allow to use single DTS on multiple boards with different mapping of external IRQ numbers. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>
