[yocto] Build the kernel for I.mx6 board

[vinod kumar]

Hi Ronaldo,

Thanks for your kind support.

I think there is no way to clean the output directory. When I run the below
commands (as you suggetsed):

   - *bitbake -c clean linux-imx*


   - *bitbake linux-imx -c cleansstate*


   - *bitbake linux-imx -c cleanall*


So all of these commands delete the contents of
git(build/tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/3.10.17-r0/git/)
directory, which I don't want. Because I want to make a zip directory
without compilation, having the contents of git directory.

And also I don't know from where *bitbake core-image-minimal* fetch the
contents of git directory.
