Hwpacks for OE builds?

hi there,

i am aware and familiar with hwpacks that were initially designed and used to generate ubuntu/android Linaro images.

however i don't know if hwpacks are being used for OE images nowadays? OE has intrinsic mechanism to generate/construct full images which include machine dependent binaries as well as generic components. So are we still using hwpacks for building OE images somehow or not? Can someone point me to relevant documentation?

in the short future i will have to build OE images for a couple of different h/w boards, so i am trying to understand the process to do that a-la Linaro.

thanks

nicolas
