run "make caravel-sta" error - When I get project from `git clone -b mpw-8c https://github.com/efabless/caravel_user_project`

When I get project from from TAG=mpw-8c as below and found error in "make caravel-sta"

$ git clone -b mpw-8c https://github.com/efabless/caravel_user_project

error log when run "make caravel-sta"

exec> read_spef -path chip_core/soc.core.RAM128 /home/tonyho/workspace/debug/d3_caravel_user_project/caravel_user_project/mgmt_core_wrapper/signoff/RAM128/openlane-signoff/spef/RAM128.nom.spef

solution - update Makefile to use git checkout $(MPW_TAG)

I can workaround this issue by update Makefile

    #( cd $(TIMING_ROOT) && git pull )
    ( cd $(TIMING_ROOT) && git fetch && git checkout $(MPW_TAG); )

Makefile update commit link

My question is, does efabless support using mpw-8c for verify my design? or other stable tag or branch for user to verify user_project?I want to base on a stable tag or branch in https://github.com/efabless/caravel_user_project to run the tape-out flow then switch to final tape-out target in chipIgnite Shuttle (we still not decide the target).

The main branch of caravel_user_project is the stable branch, and using make setup it will pull the stable branches of all the dependencies.
