All,

We have our normal call at the normal time and place today. 3 PM UTC / 11 AM US Eastern Zoom: [1]     Meeting ID: 961 7042 8801     Passcode: 8250

Last meeting was on May 17 and we discussed Franks DTB nee format page: https://elinux.org/New_FDT_format

Today I would like to start with Heinrich's DT signature patches / proposal.  (He has been waiting a while.) [2]

I would also like to discuss how we make concrete progress on the new DTB format via shared experiments as suggested by Simon last time.

Other topics welcome.

Thanks, Bill
