I'll let Sagar clarify further. 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.
