Description

This PR https://github.com/lowRISC/ibex/pull/311 introduces Simple System. It allows you to build programs and easily run them on a basic Ibex system.

It shares many commonalities with the riscv-compliance system and the FPGA example. It should be possible to refactor these things so they are all working off the same base.

In addition it would be useful to add debugging support into Simple System to demonstrate how to setup a working debug environment. Though this may draw us away from it being a simple system so perhaps it would be a new example derived from Simple System.

Research direction

Start by reviewing PR #311, then compare the Simple System with the riscv-compliance system and FPGA example mentioned in the issue. Determine whether a shared base is feasible and whether debugging belongs in Simple System or a derived example; done means the relevant systems use the common base and the debugging example has a defined scope.
