Here is my patched fork of the ara repo: https://github.com/PhilippvK/ara/tree/patch-mcounteren

Some of the Ara-specific ELF sections are not handled by https://github.com/tum-ei-eda/mlonmcu/blob/main/mlonmcu/target/elf.py yet:

WARNING - ignored: .bss.app_workspace / size: 24
WARNING - ignored: .bss.g_aot_memory / size: 160
WARNING - ignored: .l2 / size: 8

I think .l2 can be ignored, while everything starting with .bss should go into ram_zdata.

Followup tasks:

Edit clone utility in mlonmcu/setup/utils.py to accept an optional submodule_paths argument.
Add mlonmcu/setup/tasks/ara.py implementing _validate_ara and clone_ara (do not build HW here, just clone and apply patches, only clone relevant submodules!)
Add mlonmcu/setup/tasks/verilator.py implementing _validate_verilator, clone_verilator and build_verilator
Add resources/templates/ara.yml.j2 where clone urls for ara and verilator repo are defined and ara target and vext feature is enabled.

TODOs for me:

[ ] Add RVVTarget and RVPTarget Base classes to move extension handling out of actual targets.
[ ] Remove out return value of get_metrics function and create output Artifacts instead
