Docs: tidying
- Use `:file:` role for file names, as well as `:makevar:` and `:program:`.
- Remove deprecated `linux-arm` and `linux-riscv64` oss-cad-suite targets.
- Add link to ABC.
- More (and better) links to code examples.  Formatted `:file:` text with link
  to source on github.
- Includes a few extra todos (mostly picking up inline code blocks and a couple
  intro reminders).
- Fixing a few missing `:yoscrypt:` and `:cmd:ref:` tags.
- Reflowing some paragraphs for spacing/width.

Docs: work on selections.rst
Highlighting the difference between `select prod %ci` and `select prod %ci2` by
introducing `sumproud.out` using the `dump` command.

Playing around with advanced cone example code.

Docs: some restructure of advanced section
- Filling out index descriptions for `using_yosys` and `using_yosys/synthesis`.
- To discourage skipping over these index pages, the toctree in
  `using_yosys/index` is hidden and instead has inline links to the two
  subsections.
- Tidying todos.
- Moves technology mapping to `techmap_synth`, leaving the techmap by example in
  the internals section. `yosys_flows` gets split up, with the coarse-grain
  intro replaced by `synthesis/index`, the extract pass moving to
  `synthesis/extract` and model checking to `more_scripting/model_checking`.

`code_examples/macro_commands` against the current yosys build. Format similar

Docs: reworking scripting_intro
Now comes *after* example_synth, with references back to it.
Includes some minor adjustment to the `fifo.ys` script to better demonstrate the `select` command.
Still needs an updated section on `show`.

Also includes some other minor updates.

Also some other minor tidying.

Docs: optimization passes
Working on `opt.rst`.
Replace the hardcoded `opt` psuedo code listing with a `literalinclude` from `/cmd/opt.rst`.
Reorder and update `opt_*` list to match current `opt`.
Expand sub-section titles with the function of the pass (keeping the `:cmd:ref:` part at the end to prevent the Esbonio error in vscode when a heading starts with a directive).
Move comments about `clean` and `;;` being aliases into final `opt` subsection.

Also renames `Test suites` -> `Testing Yosys`.

example_synth: tidying
Adds note on `+/`.
Clarifies that we can't entirely skip loading `cells_sim.v`, and then mentions it again later once we need it.

example_synth: hardware mapping
Filling out the hardware mapping sections, and actually highlighting the changes in schematics instead of just the memory block.
Also includes Part 4 of the coarse-grain rep, looking at `memory_collect` and putting the `synth_ice40 -top fifo -run :map_ram` command in its own (sub)section.
Includes a `no_rw_check` section label in `memory.rst` for reference (because I can't remember how to reference by heading).

Not sure about the opt output after map_ram section which has an open TODO, and the final steps section is also still open.

docs: work on example_synth
Split hardware mapping from `fifo.ys` into `fifo_map.ys`.  Reduces size of `fifo.out` log and allows separate yosys calls in the makefile.

Some tidy up and minor changes in `fifo.ys` for better discussion.
Filled out note on `clean` (changed from `opt_clean`) and introduced `;;`.
Highlighted `$memrd` and added a paragraph about it.
More detail on the flatten and merging of `fifo_reader` block.
Brief discussion on the changes from `$memrd` to `$memrd_v2`.

First pass example_synth done
Split coarse grain representation into 4 parts, loosely: fsm/opt, other optimizations/techmap/memory_dff, DSPs, alumacc/memory -nomap.
Split hardware mapping into subsections as well: memory blocks (map_ram and map_ffram), arithmetic (map_gates), FFs (map_ffs), LUTs (map_luts and briefly abc), and other (map_cells and a note on hilomap and iopadmap).

Also add `-T` flag to Yosys call to remove footer from log output.

More work on example_synth
Added highlighting in (most) schematics.
Written down to end of coarse-grain, with a couple of TODOs for filling in gaps.
Includes `techmap_synth.rst` stub.

Switching example synth to fifo
Fifo code based on SBY quick start.
Instead of showing the full design we are (currently) focusing on a single output (rdata), using `%ci*` to get the subcircuit it relies on.

Initial synth_ice40 example
Overall structure in place to match the iCE40 flow.
Still needs a new example design, and more text for the later sections (which the counter doesn't cover).

Add cell_libs.rst
Updates code examples, removing `counter_outputs.ys` in favour of a single script.  Also adds a .gitignore for the output file `synth.v`.
`example_synth.rst` still pending updated example.

Working on extensions doc
Moved the last files out of the resources directory.
Some tidy up/reformatting of the extensions to allow literalincludes from `my_cmd.cc`.
Most (all?) of the getting started guidelines file is either in the quick guide section, or sections referenced by it.  Instead of including it verbatim, we'll instead just leave a reference to it but then jump straight into the quick guide.
Include an image for the absval generated module.  Still needs more surrounding text but it's good enough for now.

Also includes some other minor tidying, including removing the no longer used abc_01 code example.
