Specification of ARM memory features and related discussion of said features

Hi,

I'd like to attend the ARM summit to discuss the specification of various memory features. Most devices right now have relatively simple memory layouts but as ARM catches up with x86 or other arches in terms of memory features, we're going to need a good way to specify all the necessary details. Possible topics:

- Tradeoffs of complete removal of regions of memory via memblock_remove vs. passing in regions of memory
- Defining memory of different interleaving/speeds
- Defining hotpluggable/power-offable memory
- NUMA or NUMA like behavior
- bootloader specification of memory features vs. devicetree specification of memory features
- Specification of 'software' memory maps with features such as CMA[1]

I'm mostly interested in devicetree specification but I'm also interested in discussion of any of the features themselves and what ARM would need to match other arches.

Thanks,
Laura
