commit 7d37cb0986853d179b9724ced4e4808f9699b2fb
Author: Caleb James DeLisle <cjd at cjdns.fr>
AuthorDate: Fri Sep 12 06:43:21 2025 +0000

    econet: Clean up kernel config and move subtarget devices into own file
    
    The kernel config accidentally contains CONFIG_UBIFS_FS_AUTHENTICATION
    which select a number of other unnecessary components, remove them.
    
    The target has at least two subtargets, only one is currently
    implemented. Move the Device builds into a file for this subtarget.
