The purpose of this message is to inform your of an upcoming change in the way that NXP distributes source code for Layerscape devices. While source code has previously been hosted on Code Aurora, NXP is now consolidating all source code repositories on GitHub, and recent software releases are posted to that. Notice about this upcoming change has been posted on CodeAurora for a long time:

Customers access source code repositories when they are compiling software binaries. Source code may no longer be available on Code Aurora as soon as April 1st 2023. If a customer uses a build script that attempts to pull from Code Aurora after April 1st, the build may fail. It is simple enough to alter the script to access GitHub instead. If you get questions from customers on this, you may share this FAQ with them.
