Eco the same reply here. I am not sure what you mean. We verified on FPGA & Emulator,
and the logic is pretty much close to the real silicon. I did mention that in the cover letter as well.
I am new to Linux, so I am wondering if there is a Linux upstream guideline mentioning
that pre-silicon software is not allowed to upstream? Hope there is an updated Linux
upstream guideline that benefit other vendors.
