[Sound-open-firmware] Design document - topology, scheduling et all

Hi all,

First of all I'm now in the phase where I only need to implement the DMA driver for i.MX and create the topology file.

Few questions:

1) Is there any simple scenario (topology file) where I could test that scheduling, ipc, pipelines, etc works without the DMA? It is my first time using topology and I'm still yet to get around the m4 topology description.

2) Is there any design document for the SOF architecture. I'm still yet to understand how components and scheduler interact.

thanks, Daniel.
