Integrates lowrisc_opentitan as a local path dependency and applies patches to rules_rust, rules_rust_bindgen, and toolchains_llvm to support Rust 2024 and allow sub-module LLVM toolchain usage. TAG=agy CONV=6581f846-3452-4ca4-b0d0-1eaa6c5c5aa3
Adds the //third_party/lowrisc_opentitan package with transitioned targets (opentitantool, opentitanlib) to configure preferred build features (disable OpenSSL, enable only chipwhisperer/hyperdebug/verilator transports). TAG=agy CONV=6581f846-3452-4ca4-b0d0-1eaa6c5c5aa3
This eliminates the `opentitan_runner.py` wrapper script and generates orchestration bash scripts directly in Starlark. - FPGA and Silicon targets are executed in two stages: board setup (via opentitantool) followed by the test command/harness. - Verilator targets use a single opentitantool invocation. - Supports custom `test_cmd` and `test_harness` attributes. - Uses opentitantool from //third_party/lowrisc_opentitan.

opentitanlibfrom the master branch of upstream opentitan.opentitanlibfrom upstream. This enables writing host based test harnesses that have more complex interactions with the DUT than can scripted with opentitantool. The upstream opentitan patch is complex and under review; temporarily point to my fork of opentitan.opentitan_testrule to support test environments. A test environment is a bazel provider that references resources needed by a particular testing platform (e.g. fpga board, silicon, etc).See
target/earlgrey/env/README.mdfor details about test environments.
