Research direction

Start by tracing how Heap is initialized and how the allocator currently receives a single memory region, then compare that with the ESP32 linker regions dram_seg and dram2_seg used through esp-hal. Done means one Heap can use both regions, or more regions if supported, without requiring users to configure multiple heaps.

Description

help wanted

The ESP32 (using esp-hal) has two memory regions that are usable, in the linker scripts as dram_seg and dram2_seg. Currently, this dram2_seg is unusable unless a user is to setup multiple heaps which is annoying to use. Can support be added to allow one Heap to both (or even more) regions of memory?
