[tnmysh]

Examples and demos should be moved to new repostiory: openamp-system-reference.

This should not cause any backward compatibility issues.

We should define the functions that a bare-metal BSP needs to implement.

We need to work this with a baremetal demo on at least two platforms. (Xilinx and TI?)

Target resolution 2024.10

Discussed in 2/21/2024 OpenAMP System Reference call:

• Don't have to move existing demos, can start introducing what works with the existing Linux apps & once have working in System Reference, can delete the old stuff. This would allow us to architect the demos without having to deal with legacy history.
• Matrix multiply: TI found it useful
• Libmetal as API provides abstraction layer. Based on what we do for the more stable operating systems. OpenAMP repo also has some cleanup to be done to split what should go into BSP vs. OpenAMP project.
• How to make same baremetal app work on different vendor platforms? Do we want to keep them or move to silicon vendor repo? Baremetal BSP should come to Libmetal & baremetal BSP should hold the glue, glue should not go in libmetal.
• If there are API functions that don't make sense on 1 vendor's platform, can have NOP/return success
• Demo apps in open amp library -> should be able to make it generic. Each vendor should provide their own low-level functions & BSP additions.
  **- Recommend for any new demos to go to System Reference
• Would like to target October 2024 release to move the demos to System Reference.**
