The top Rashi on Menachos 57:2  if I'm reading it correctly  adds some information as an aside  stating that both Rabi Akiva and Rabi Yose Hag'lili derive from "asher takrivu" that a mincha of a kohen (or perhaps he means specifically the inaugural mincha of a kohen) and the inaugural mincha of the kohen gadol may not be made chametz
