Hi, Since the number of configuration files is increasing, let’s move the configuration files (ConfigXXXX.cmake) into specified directory. This would reduces the files under root directory and makes the structure more clearer.

I have created the issue and patch for it: https://developer.trustedfirmware.org/T394 https://review.trustedfirmware.org/c/trusted-firmware-m/+/1234

IMPORTANT NOTES: To be compatible with the existing building configurations, the existing configuration files have been forwarded into the corresponded configuration file under ./configs. Which means there are two set of configuration files under sources tree at current – but this will change soon. There is a warning while you are building with root configurations files: “Please use the configs available in the ./config sub-directory.”

So please:

- If you are planning to create new configuration, create it under ./configs instead of root directory - The reference of configuration files under root directory will be removed soon, please change your build system setting to reference the configuration files put under ./configs

Any feedbacks please reply this mail or put comments under the issue, thanks 😉
