CsrAccessPlugin

class CsrAccessPlugin extends FiberPlugin with CsrService

Implements the RISC-V CSR read/write instructions, aswell as provide an API for other plugin to populate the CSR space. In other words, this plugin do not define any CSR, but provide an API to define them (that API is defined in CsrService).

To help with the FMax, CSR accesses are implemented by using a state-machine. Accesses are done over 4 cycles : idle -> read -> write -> completion

This maybe a bit overkilled, but as the CSR access isn't critical for the IPC, better to much cycles than not enough.
