== Device Tree == * Posted the patch that builds .dtb files for boards enabled by config option. Got good suggestion from Rob Herring to improve. Will re-spin soon. * Tried to play linux-linaro-natty tree a little bit to get .dtb file built in linux-image-*.deb. But I can not post patch for merging until John Rigby sync this tree with Nico's latest kernel tree. * Will work on l-m-c to get .dtb installed on boot partition. == Misc == * Read the thread of Linus' complaint on messy ARM platform codes. -- Regards, Shawn

[PATCH] arm/dt: Add a make rule to build dtb for enabled platform

by Shawn Guo

It's based on commit fe8e6d0b0e601ca0a63fe768d4b812d5a45a9da7 "arm/dt: Add dtb make rule" from Rob Herring. With 'make ARCH=arm dtb', it builds Device Tree Blobs for those platforms enabled by CONFIG. Signed-off-by: Shawn Guo <shawn.guo(a)linaro.org> --- This patch works against Linaro kernel tree.

[git pull] Devicetree support for rebuild linaro 2.6.38 branch

by Grant Likely

Hi Nicolas, Here are the device tree changes for 2.6.38 rebased onto your new branch. I had to rebase instead of just asking you to pull directly since I have a number of patches in my test tree that are merged in a different form in your tree. For those of you working on DT support for the 11.05 release, please test against this branch and make sure everything is still working for you. g.
