Add pin allocation table and other supporting development documents on repository
This is actually an issue to myself that I'm posting for proper project documentation. In the last week I have built some supporting python scripts and tables (and are doing a bit more yet to come) both to help verification and to elaborate better propositions. It is a huge board with very complex connections, so these documents surely helps us.
To help with our discussions, a Google Sheets version of said table is here: https://docs.google.com/spreadsheets/d/1jqtvYwF3Ozs9X-FW3CjEMU27Bz1tAkfl5G_oD3gFZpk/edit?usp=sharing
There are still some checks missing, I'm doing then still today. I intend to check on electric compatibility of the LPC1768 pins (this has already been a problem, LPC pins are not homogeneous) and put this on this table.
