Hi,
RFC as only build tested. Need to get early feedback before I spend more time on this.
Newer TI boards (AM6/J7) are using a custom logic to detect expansion cards and set a 'name_overlays' environment variable. Then DT overlays are applied by again custom environment scripts during boot.
Instead of that migrate to using the Extension framework. This allows the user to call 'extension scan' and 'extension apply' commands to detect extension cards and apply the DT overlays respectively.
For Booting, I expect distro boot scripts to already support the extension framework via following environment 'extension_overlay_cmd' and 'extension_overlay_addr'. i.e. include/config_distro_bootcmd.h
cheers, -roger
