Each device can be configured to have up to 8 NTB functions and can support up to 8 CPUs/roots.
Each device can have up to 64 masters ID for address and ID translations.
Each NT port has six BARs, where each BAR opening an NT window to another domain.
Lookup-table translation divides the BAR aperture into up to 24 segments, where each segment
has independent translation programming and is associated with an entry in a look-up table.
Doorbell register is used for event signaling between domains, where an outbound doorbell bit sets
a corresponding bit at the inbound doorbell in the other domain.
Message registers allow mailbox message passing between domains -- message placed in the
inbound register will be seen at the outbound register at the other domain.
