From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> The AGBBUSY# bit in INSTPM caught my eye while reading the code and having the spec open at the same time. This series makes the code match the spec, and also closes a potential race condition (which may or may not be real, depending on how the hardware works).
