this is the Fetch ospec()

https://git.libre-soc.org/?p=soc.git;a=commitdiff;h=f1c63229cdf94d9fbca54086ff13d6a149245814

class FetchOutput:
    def __init__(self): #, svp64_en):
        self.state = CoreState("core_fetched")
        self.raw_insn_i = Signal(32) # one raw instruction
        self.bigendian_i = Signal() # bigendian - TODO, set by MSR.BE

real basic, but contains everything needed by the Decode phase.
