SPIRAM

[TyberiusPrime]

So I managed to compile micropython for the Ai-Thinker (using https://github.com/othiman/esp-adf-ac101, but it's the samething right), but it's not using the SPIRAM.

Does anybody know what I need to change to enable it?

Ok, I got it running. Micropython is still only using 4mb of the 8 on the module,
but that's a micropython thing - the boot messages correctly detect 64Mbit of SPIRAM.

Here's the changes I made
