LICENSE

This project is a collection of components with mixed licenses. Each
file carries its own SPDX-License-Identifier where applicable. The
overall project is distributed as follows:

  - Linux kernel patches under patches/linux/  — GPL-2.0
  - Boot shim under linux-native/              — Apache-2.0 OR GPL-2.0
  - C6 slave fork under c6-slave/              — Apache-2.0 OR GPL-2.0
    (inherited from upstream esp-hosted-ng)
  - Tools under tools/                         — MIT
  - Buildroot overlay scripts                  — GPL-2.0
  - Docs                                       — CC-BY-4.0

The combined work, when distributed together, is GPL-2.0 because the
kernel patches dominate the licensing footprint.
