Hi Nathalie,

In addition to the point below, I would also like to discuss a new topic: discovery of PCIe apertures based on Device Tree overlays on ARM and x86. It is another example of using Device Tree to describe "more" compared to what it is commonly used for. In this case, it is used to describe PCIe apertures and other details of a PCIe device at runtime. Lizhi (CCed) will introduce the topic. It is a bit different from the usual System Device Tree discussions on these calls, but I think it is relevant and to the audience.

Cheers,

Stefano

Hi all,

Notes from the previous call https://github.com/OpenAMP/open-amp/wiki/System-Device-Tree-Meeting-Notes-20...

Action items from previous call:

• Stefano: To raise Q w/ Rob in email
• Stefano: Could write System DT part of spec just to add secure-address-map not tied to secure-bus. Secure-address-map could work for range specified through simple bus. Had always thought of the 3 features together, but this can be split out.
• Stefano will write out proposal
• Secure-address-map
• What can be done simpler for simpler cases?
• Stefano: Will continue conv w/ Rob about ranges & reg & what can be done to avoid duplication
• Nathalie & Stefano: Set up another call w/ Rob.
