I've been in touch with some of the team at Marvell. They have some
additions that should hopefully resolve some of the queries/concerns
around the clock configuration. I've also got a minor update to add a
comment about the PPI for the EL2 virtual timer based on Marc's request.
I expect to send a v9 with those changes (and anything else anyone has
feedback on related to this series) sometime next week.
