The goal here is to guarantee that the SDK gets DRAM for the heap requests that are made during SDK API calls. To accomplish this I rely on the SDK to only use the portable heap functions: pvPortMalloc, pvPortCalloc, pvPortRealloc, and pvPortZalloc. I add a thin wrapper to these functions to switch to DRAM.
I am not sure about the lwIP library, it appears to use both malloc and the pvPort... APIs.
