Here are some brief notes from the meeting.

If nothing else as a showcase on how much we miss Nathalie when she is on vacation ????

Krzysztof Kepa – GE Mathieu Poirier – Linaro Etsam Anjum – Mentor Anrnoud Pouliquen – ST Loic Pallardy - ST Suman Anna - TI Dan Milea – Wind River Mark Dapoz – Wind River Tomas Evensen – Xilinx Stefano Stabellini – Xilinx Bruce Ashfield – Xilinx Ed Mooring – Xilinx Ben Levinsky - Xilinx

Stefano went through slides. Overall idea:

1. Specify remoteproc channels with minimal information in System-DT in a way that is as common as possible for all vendors.

In particular, we are avoiding to have to specify the same memory regions in more than one place. A resource group is specially marked to contain most information. 2. Use Lopper to create the vendor specific remoteproc specification Generating reserved-memory, etc. information that has duplicate information. For the time being, no plans to unify the vendor specific information that goes into the traditional device tree for Linux 3. Later (or in parallel), but without making it a gating item, start discussions on what we can do to unify the vendor specific information in the traditional DT

Can anyone point me to some examples of vendor specific information referred to here?

Some of the other attendees might have better examples than this. The ones I was mentioning this morning are the "mboxes" and "mbox-names" properties you can see in the "output.txt" example. Also the memory regions listed under the "memory-region" property and under "reserved-memory".
