Boris, perhaps you should also update the Kconfig entries for RTC_DRV_AT91SAM9_RTT and RTC_DRV_AT91SAM9_GPBR to clarify that they are only used for legacy booting (and otherwise have no effect)? > With that, good description: thanks! > > Acked-by: Nicolas Ferre <[email protected]> > > So, now we can think of what to do with the series: > > - Johan, do you want to "Ack" it?
