Hi Paul, I see your branch has the DT where the hart0 is marked disabled and M-mode interrupts are masked in PLIC DT entry. IIRC, your v1 patch series for DT didn't have those fixes.
I am assuming that you are planning to upstream these changes as well and it will be part of your v2 patch. Is that correct ?
