Hi Alex,
I was reading your notes for DT management
Alex: Have logic in firmware that can enumerate "Hat"s and create EFI object for them. These objects could then be backed by DTBOs - either by grabbing them from the device (EEPROM) or by a stored blob in firmware. >Grub for example could then also be taught about these objects and DTBO support, so an OS could store its own overlays. EDK2 has the hat logic support today and already does create objects.
I am not sure, where you want to store DTBO in EEPROM or on some other partition/media. If this is EEPROM then I hope firmware is stored on this as well. Then we shouldn't expose EEPROM to OS.
Regards Udit

Hi folks,
Weekly EBBR meeting starts in about 1/2 hour. Dial in details below. Once again the agenda is very short, but I'll open it up to other topics after action item review. I think there was some interest in talking about DT overlay handling.
Notes are being captured in the following Google doc. I would greatly appreciate help with taking meeting minutes.
