Thank you for the information.
Is it about adding support for the xtensa build system (toolchain)? Is it work for heterogeneous SoC (CPU/ARM + DSP/xtensa) as well?
I can think of few ways
build your Xtensa firmware outside yocto and let yocto package it via recipes for prebuilts and build ARM system with yocto should work well
second option is to integrate Xtensa support into OE and then use multiconfig feature to build firmware for heterogenous systems.
this will be preferred and forward looking for future but it will be

I think we do not have support for Xtensa architecture working out of
box upstream. Although it should be possible to add it with little
effort, but no one has spun patches to do so
