Andrew - do you plan to add it for the -next?

I also need to implement at91 sram support for ethernet, spi and other drivers

and as Russell point other ARM need it also for consolidation.

And I'll not be able to use Russell's patch as I've to manage two sram in one
allocator on at91sam9263

Tks by advance
