DeviceTree - timvideos/litex-buildenv GitHub Wiki

We want to use DeviceTree to allow MicroPython to automatically customize itself based on the FPGA configuration.

This involves 3 parts;

• Making LiteX / Migen+MiSoC generate DeviceTree - https://github.com/fupy/issues-wiki/issues/6
• Making MicroPython understand DeviceTree - https://github.com/fupy/issues-wiki/issues/7
• Adding support for peripherals under MicroPython

This has other useful advantages;

• LiteX / Migen+MiSoC supporting DeviceTree makes porting Linux to it possible.
• MicroPython understanding DeviceTree makes it easier to port MicroPython to more SoCs.

Useful DeviceTree links

• DeviceTree: The Devicetree Specification - https://www.devicetree.org/
• Device Tree for Dummies - Free Electrons
• libfdt - https://github.com/dgibson/dtc/tree/master/libfdt - http://ozlabs.org/~dgibson/
• https://pypi.python.org/pypi/pyfdt/0.3 and github https://github.com/superna9999/pyfdt
  • pyfdt looks like it might work. It uses struct, json, os (which all appear to have MP equivalents), strings, and copy (which don't) standard library functions. Perhaps a upyfdt might be forked from it.
