Thanks everyone for taking your time to review the RFC.
Regarding device discovery:
Every device sends a "PRESENT" message when it comes up. Every device has
48-bit address like Ethernet and spec lets upto 256 devices (each getting
8-bit logical address) on one bus.
The device can report anytime (when it's plugged in, when a dynamic module
powers it on etc.)
Typical use case will be to have it board-specific but as Mark
mentioned,we may have plug-in cards with slimbus devices so we want
dynamic support as well.

Thanks-
