[PATCH] remoteproc: xilinx: add mailbox channels for rpmsg

by Tanmay Shah

This patch makes each r5 core mailbox client and uses tx and rx channels to send and receive data to/from remote processor respectively. This is needed for rpmsg communication to remote processor.

OpenAMP System Reference Webinar video - opportunity to review before submission

by Chan King Choy, Nathalie

Hi team, Nice work on all your slides and recordings! Thank you so much for submitting recordings early, so that I could get most of the edits in place before the end-of-quarter craziness that I got swept up in this week. Here is the webinar video combined end-to-end if anyone wants to watch it. I have only watched the components on 2x and the transitions at normal speed. I'll watch the whole thing at normal speed over the weekend. https://drive.google.com/file/d/1XcQGtFZSDhbuj8v7vwb8GGcVyNZvfCFw/view?usp=… The components are in the release candidate folder: https://drive.google.com/drive/folders/1rZbnPeR2Ew5hTXz7N91YHRCQtDMEwawY?us… Updates since what we discussed on Nov 29th: * Bill intro & wrap up slides now use devicetree. * Arnaud's new recording footage is used * Dan's hflip video is incorporated * I added a section where Tomas introduces himself & Bruce from the discarded footage, because the good take didn't include it. * Sped up the "dead time" sections of Arnaud's, Dan's & Tanmay's videos (e.g. boot). Bruce's demo didn't have any long typing/execution gaps when he wasn't speaking. If I sped up execution, I annotated for transparency with a green box with white text. If I just sped up stuff like typing/scrolling then I didn't add the green box annotation. * Added fade transitions between sections. * There was 1 title slide of Bill's with a page # that I tried to hide, but it shows up for a fraction of a second still because of limitations with how the fade effect works. I hide all the page #s because otherwise we were restarting numbering with each new deck. @Bill Mills<mailto:bill.mills@linaro.org>: Assuming it has no issues when I watch it at normal speed on the weekend, how to submit this to Linaro Events on Monday? If we want to share the Google Drive link with them, we have to add them to the access for this file. I will work on the OpenAMP website update & TSC email later today. Wanted to get this video out first in case anyone wanted to review it. Thanks & regards, Nathalie
