Please update this repo to the version used in the fomu-workshop

[andykitchen]

Hi!

I've been trying to build micropython for the fomu from source. Unfortunately I got a little stuck and it took me quite a bit of trial and error to realise that this repo is out of date for foboot 2+ and one needs to compile the newest version of xobs' personal fork.

My small suggestion would be adding the right micropython as a submodule inside fomu-workshop to keep that dfu image and micropython source version used to generate it matched up.

Kind regards

AK
