There is a further issue that occurred to me doing their excellent FOSDEM talk, which is that nowhere in this has any kind of verified boot scenario been discussed, and if you don't get that thinking in from the start it is very hard to wedge it in later. I think we should consider the OpenSBI in its current state a starting point for figuring out what we need to do. _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
