i2c: Type-state ArmedDma refactor + on-hw abort test

Drop the runtime `committed` flag from ArmedDma; commit(self) now consumes
the guard via mem::forget, so a committed transfer is no longer a droppable
value and Drop tears down unconditionally.

Add the two-image i2c_dma_abort hardware test (master DMA + clock-stretching
slave) exercising the commit no-op path and the timeout -> guard-drop ->
soft-reset teardown path.

Getting Started

NOTE: We are converting our build system to bazel. We recommend installing bazelisk to automatically manage bazel versions.

Available Tasks

You can run tasks using the Pigweed workflow launcher pw or bazel.

  • ./pw presubmit - Run presubmit checks: formatting, license checks, C/C++ header checks and clippy.
  • ./pw format - Run the code formatters.
  • bazel test //... - Run all tests.
  • bazel build //docs - Build documentation.

Development

The project is structured as a bazel module.

Requirements

  • Bazel. We recommend installing bazelisk to automatically manage bazel versions.

No additional tools are required - all dependencies are managed by bazel.
