Help text

The StarFive JH7100 was a test chip for the JH7110 and has caches that are non-coherent with respect to peripheral DMAs. It was designed before the Zicbom extension so needs non-standard cache operations through the SiFive cache controller.

Say "Y" if you want to support the BeagleV Starlight and/or StarFive VisionFive V1 boards.
