This shouldn't be necessary because it should never have been set.
Yes, I think so. However, I have a question about MSTATUS_MIE and MSTATUS_MPRV, will they
be set before cpu reset?
Yes, via warm reset.
I would think it would be more correct to have a positive test for RVF, rather than a
negative test for ZFINX?
It may deviate from the original value of mstatus_mask with a positive test
for RVF.
Oh, you mean misa_ext? Hmm. Interesting point.
When F extension is not implemented, FS is either hardwired to zero (without S-mode) or
optionally zero. So this looks like an existing bug to be fixed.
