case class LsuL1Bus(p: LsuL1BusParameter) extends Bundle with IMasterSlave with Product with Serializable

Define the VexiiRiscv LsuL1 native memory bus. Its memory coherency protocol is close to tilelink, but has a few minor twists : - probe request may fail in Vexii, and so, need to be retried - probe request which produce a permition downgrade will be acknoledged on the probe.rsp bus, but will also generate a write.cmd writeback (which can be data-less)

All memory transaction are assumed to be the size of a cache line, including probes.
