Feature Description

Include detailed instructions in the Chipyard documentation to debug with JTAG in simulation with OpenOCD + GDB.

Motivating Example

Need to debug simulation via JTAG in Chipyard. Chipyard links to this page, which leads to nothing.

See https://chipyard.readthedocs.io/en/stable/Advanced-Concepts/Chip-Communication.html#debugging-with-jtag. Step 3 leads to https://github.com/chipsalliance/rocket-chip#4-launch-openocd.

This leads to the Rocket Chip repo, where the README contains a table of contents with a 'Debugging with GDB' section. This link is broken and/or no documentation exists.

Here's the fixed link: https://github.com/chipsalliance/rocket-chip/tree/v1.6#4-launch-openocd (if something got removed from a git repository you can check the git history) but this doesn't look quite right...

A PR to inline these docs into the chipyard docs, since they were removed from rocket-chip, would be greatly appreciated
