Running "make linux-firmware-legal-info" with this firmware selected
generates a warning/error:

Could you add the hash for this new file, please? In:

Best regards,
Julien.

Running "make linux-firmware-legal-info" with this firmware selected
fails with error:
cp: cannot stat
'/buildroot/output/build/linux-firmware-20250627/LICENSE.cnm': No such
file or directory
This is because the license file is named LICENCE.cnm
(with 'C' instead of 'S'). See:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/LICENCE.cnm?h=20250627
Also, there is a warning that there is no hash for that file. Could
you make to also add the hash for this new file, please? In:
https://gitlab.com/buildroot.org/buildroot/-/blob/master/package/linux-firmware/linux-firmware.hash
