Ok, that sounds good to me.

Sure, I'll resubmit it to Russell via the patch system with your ack. I'll
do the same for the DEBUG_LL platform updates too.

For the cpu-mapping, I depend on:

ARM: 7011/1: Add ARM cpu topology definition
ARM: 7060/1: smp: populate logical CPU mapping during boot
ARM: 7061/1: gic: convert logical CPU numbers into physical numbers

which I can only see in Russell's for-next branch.

For the debug-ll stuff, I depend on:

ARM: 7072/1: debug: use kconfig choice for selecting DEBUG_LL UART

and conflict with:

ARM: 7097/1: debug: Move DEBUG_ICEDCC into the DEBUG_LL choice
ARM: 7096/1: debug: Add UART1 config choices
ARM: 7116/1: debug: provide dummy default option for DEBUG_LL UART choice
ARM: 7073/1: debug: augment DEBUG_LL Kconfig help to clarify behaviour

so it's probably easier to go via Russell this time.

Cheers,

Will
