Hello All,

RPMsg in U-Boot is under development. First proof of concept patch v1 was sent to upstream mailing list as RFC patch here: http://patchwork.ozlabs.org/project/uboot/list/?series=365

Here is the video of demo of RPMsg framework introduced in above patch series: https://www.youtube.com/watch?v=PxGNR_FYGt8

This document explains patch series and motivation to introduce RPMsg in U-Boot and future work that needs to be done: https://drive.google.com/file/d/1Bjtzj58klMPVuWEtRK89oyem7_Hdajn8/view?usp=s...

This patch series is very basic implementation of virtio based RPMsg framework referenced from the Linux kernel. For now, U-Boot is communicating with remote processor over fix hard-coded endpoint. More advance features such as name-service, multiple endpoint support etc.. will be added in coming revisions of this patch series. Meanwhile, please feel free to review existing work and provide review comments and any other suggestions.

Thanks, Tanmay
