Ok. Then we're on the same page here.
Because PicoRV32 is using the axi bus as well, we can't use this core for our
We will have to bootstrap our own SoC/MCU using Chisel3 and rocket-chip as a
basis, essentially stripping the rocket-chip of all AXI-stuff and re-adding
the features, but hooked up directly over TileLink instead.
I guess the only reason eFabless with their Raven didn't get into trouble yet
is because there were just some managers at ARM hysterically laughing when
they've read the tape out volume and orders of this MCU.
But as soon as we start providing a free technology node and open layout and
sell the part as off-the-shelf part they might become pretty nasty and try to
hurt us any way they can, including law-suits (even though futile, as we've
