Is anyone working on adding a sifive-u74 core to the list of supported CPU types? I was looking at full emulation of the Unmatched but at the moment the best we have is sifive-u54 and I think that misses at least two CSRs the sifive-u74 has.
Does anyone have plans to add the sifive-u74, and if not, would a plan to add gradual support for it like adding CSRs 0x7c1 and 0x7c2 so we can run an Unmatched U-boot SPL against it. If not, is there a definitive U54->U74 set of public differnces around we could use to start from? I'd like to be able to run a full Unmatched image using qemu at some point to add to the current real-board testing we're doing. (I have a basic addition of the type and the two CSRs as a couple of patches if that would help as a start) -- Ben Dooks, b...@fluff.org, http://www.fluff.org/ben/ Large Hadron Colada: A large Pina Colada that makes the universe disappear.
