Adds the ability to use PSRAM and non-contiguous memory.
Example usage, add this to dts overlay:
/ {
heap_psram {
compatible = "micropython,heap";
size = <DT_SIZE_M(4)>;
memory-region = <&psram>;
};
heap_sram1 {
compatible = "micropython,heap";
size = <DT_SIZE_K(140)>;
memory-region = <&sram1>;
};
};
