metro: Bringup tracking issue

Start with the unchecked entries in base.toml, dev.toml, and lab.toml, comparing the metro definition with the cosmo-based setup described in the issue. Work through the remaining task, configuration, feature, and FPGA-blob checklist items; done means the applicable metro bringup entries are reviewed and enabled or resolved.

In #2676, we added/are adding a totally-commented-out definition for metro, based on cosmo.

However, we need everything to actually work! Here's a tracking list of things that still need to be reviewed and enabled. We can make PRs for chunks of these features at a time. This is currently structured in roughly the shape of the toml definitions.

I've marked a couple "high priority" tasks as 🚨. A couple of "will definitely be different" items are marked as ⚠️.

base.toml

• Enable measurement-handoff (this should be done as late as possible to make testing smoother)
• [mmio] ⚠️ - FPGA map may differ
• [caboose] - #2690
• [tasks]
  • [tasks.jefe]
    • [tasks.jefe.config.on-state-change] - #2691 (partial
    • [tasks.jefe.config.on-task-fault] - #2690
    • [tasks.jefe.config.allowed-callers] - #2691 (partial)
  • [tasks.net] - #2691
  • [tasks.sys] - #2680
    • [tasks.sys.interrupts]
    • [tasks.sys.config.gpio-irqs.rot_irq] - #2695
    • [tasks.sys.config.gpio-irqs.seq_irq]
  • [tasks.spi2_driver] - #2691

  • [tasks.rng_driver] - #2690
  • [tasks.thermal]
  • [tasks.power]
  • [tasks.hiffy] - #2687
  • [tasks.metro_seq] ⚠️ - A general comment is that metro will have a new sequencer FPGA image that is not common with cosmos, though for most purposes they'll look the same barring some new features around programming the Versal etc.
  • [tasks.ignition_flash]
  • [tasks.spartan7_loader] ⚠️ - A general comment is that metro will have a new sequencer FPGA image that is not common with cosmos, though for most purposes they'll look the same barring some new features around programming the Versal etc.
    • [tasks.spartan7_loader.config]
  • [tasks.hash_driver]
