LTSI Kernel Porting Information: Yocto Poky

=LTSI Kernel Porting Information: Yocto Poky=

The following shows the information of the result of porting the Yocto Poky 9.0.0 distribution with the LTSI 3.4 kernel for CuBox. Anyone is more than well come to add information here in the following format

What had been done:

 * Cherry-pick local patches for CuBox from a git repository that has been maintained by Rabeeh Khoury, who is a SolidRun Company guy, and merge them into the LTSI 3.4 kernel.
 * Make a Yocto recipe for CuBox and the LTSI kernel.

Linux Lernel
The CuBox manufacturer SolidRun is (unofficially?) maintaining a public, but not upstreamed kernel code tree for CuBox at https://github.com/rabeeh/linux althrough the latest mainline kernel may support the platform enough. The SolidRun kernel has been based on the 3.6.9 mainline kernel. So I cherry-picked all local commits from the SolidRun's kernel respository, and tried merging them into the 3.4.39 LTSI kernel. As a result, I understood a few commits were unnecessary for the LTSI 3.4 kernel, and some of commits required small adjustments becauseof the kernel version mismatch.

Finally, I merged the following 97 local patches into the LTSI kernel.

Yocto Poky
Luckily, I found a Yocto recipe cutomized for Cubox at a git repository https://github.com/dv1/meta-cubox, which has been maintained by a guy 'dv1'. So I just added two small changes into the recipe for my LTSI kernel and the latest Yocto.

Patches:
You can see the cherry-picked and merged kernel patches at the '3.4-ltsi_cubox' branch in my git repository https://github.com/matsu/linux-stable/ or clone it from git://github.com/matsu/linux-stable.git

And you can also get my Yocto recipe for Cubox from the 'ltsi' branch in https://github.com/matsu/meta-cubox.git

Notes:
I know some issues remain in my current kernel and yocto recipe. Particularly, the video decoder and the 3D graphics acceleration in CuBox SoC could not be supported yet. So I would like to resume the porting when circumstances allow...
