Thanks for your response.

I am sorry, I thought that is what meta-freescale for, right? NXP
might involve the coding, but is it integrated and released by Yocto /
OE https://git.yoctoproject.org/cgit/cgit.cgi/meta-freescale/, right?
I cloned meta-freescale from Yocto project:
git://git.yoctoproject.org/meta-freescale, I am sorry, I really lost.
