Similar to other nodes in this file, here and elsewhere use
bootph-all
Okay. I will switch to bootph-all
Is'nt esm configuration just needed during pre-ram?
This is needed only the R5 SPL phase. So bootph-pre-ram looks better suited.

Vignesh,
This ESM nodes should be bootph-pre-ram. I will keep that flag as is.
Best Regards,
Keerthy
