I won't pretend that I understand why quite so many people are required to add a few definitions of the spec! Nor can I be bothered reading 12 revisions on lore to find out why it was done this way... They do seem to align with what is in the latest release, so: Reviewed-by: Conor Dooley <conor.dooley@microchip.com> I also noticed that you missed some tags from the v12 submission. Eg Heiko's here: https://lore.kernel.org/linux-riscv/2096011.OBFZWjSADL@diego/ There's also one for patch 1: https://lore.kernel.org/linux-riscv/5335635.Sb9uPGUboI@diego/ Thanks, Conor.
