Add a Tutorial tree that mirrors the roadmap from Phase 0 through Linux bring-up. Each phase and subphase gets a short learning note with consistent sections for context, goals, new concepts, mental model, learning tasks, pitfalls, tooling, testing, and references. The tutorial material is intentionally explanatory rather than implementation code. It gives a systems-oriented learner enough FPGA, SystemVerilog, RISC-V, firmware, and Linux bring-up context to approach each roadmap phase without turning the notes into copy-paste RTL.
FPGA-Core Tutorial
This tutorial tree follows ROADMAP.md. Each phase and subphase has a learning note
with the same structure:
- Context
- Goals
- New Concepts
- How To Think About It
- Learning Tasks
- Pitfalls
- Tooling And Testing
- References
The notes assume strong Linux/systems experience and beginner-to-intermediate FPGA and digital-design experience. They intentionally avoid giving implementation code. The goal is to explain what to learn, what to verify, and what mistakes to avoid.
