Cool Things To Note

• python -m litex.tools.litex_read_verilog ./rtl/flipPwm.sv allows for auto-gen of the LiteX Class needed to create an instance, however it does not set up the CSRStorage.
• Load Application Code To CPU
• Use LiteScope To Debug A SoC
• Use GDB with VexRiscv CPU
• Run Zephyr On Your SoC
