[Xtensa] abandoned?

Sorry for the junk issue; but just wondering, is there an Xtensa maintainer?
I've been stacking up backend issues and workarounds for months, and there seems to be no action (or even comment) on any of the Xtensa issues I've lodged... is it a dead target?

Espressif alone have shipped 10s of BILLIONS of cores... that's a lot of deployed devices. It's a very useful target!

Review the existing Xtensa issues and backend workarounds referenced in the report, then determine whether an active maintainer or documented ownership exists. This issue is complete only when the target's maintenance status and a responsible contact or next step are established.
