    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-
    -Sagar
