The host needs to set both. Without Master Enable an agent is not
supposed to initiate transactions on the "bus", that's the meaning of
that bit.

This is correct and host set both bits: Master_Enable and Discovered.
The documentation change above is related to event that triggers
discovery process.
In this context the change shown above is sufficient.
Please see the original code patch submitted by Liu Gang.
