Making a KiCAD schematic symbol for the STM32MP257 around other projects.
It's taking a while because I haven't found an easy machine readable source of data and there's a *massive* number of alternate functions on the pins.
The symbol has something like 20 sub-components now.
@azonenberg CubeMX will now generate Kicad files for parts. It'll even group the pin assignments if you make any, but I don't like the way it orders them. Also, maybe there is XML data for the part inside of Cube files?
