Overlay manager processes DT entries on demand.
It is chosen by CONFIG_OF_OVERLAY_MGR option.
These entries can be chosen from kernel command line:
overlay_mgr.overlay_dt_entry=hardware_cfg_0
DT contains main overlay_mng entry with all possible
HW config setups. And then kernel command line option
will allow to choose between them.
Kernel DT entry:
overlay_mgr {
compatible = "linux,overlay_manager";
hardware_cfg_0 {
overlay@0 {
fragment@0 {
__overlay__ {
};
};
};
overlay@1 {
fragment@0 {
__overlay__ {
};
};
};
};
};
