Hi, I noticed your RISC-V patches on the mailing list and had a question
that I think you may be able to answer. Has anyone defined a RISC-V platform
yet? What I mean is defining what devices would be found on a RISC-V
motherboard. I do hope to see RISC-V based desktop systems one day. But
before that day can come the platform for this chip would have to be
established. Could the SiFive board be the basis for such a standard?

It really depends what you mean by a standard platform. At the moment
the SiFive HiFive Unleased board is the only ASIC that can boot Linux.
So that really is the "standard" RISC-V board. It is a pretty basic
embedded board though, so it can't be considered a "standard" RISC-V
desktop. There is a virt board in QEMU (which is similar to the HiFive
Unleashed) that is a good go to for QEMU work.

The HiFive Unleashed is the defacto standard RISC-V embedded Linux platform right now, but there will be a RISC-V platform specification that defines proper standard platforms of various types. This effort hasn't been started yet, but it should be done sooner rather than later.
