Correct: full access to the inbound.

According to the Freescale documentation, outbound is just as valid for
endpoint as for root complex - indeed, to generate MSIs from software

I am programming BOTH the inbound ATMUs to make PPC memory available to
the root complex, AND programming outbound ATMUs to enable the

Not quite: I can also read the BARs that I program, and the memory
behind them on the PPC.

As far as I recalled on 4xx the u-bo
I am trying to get the PCIe interfaces of a Freescale MPC8641D working in
endpoint mode (i.e. as a PCI device rather than a PCI root complex host).
I can get the device to show up on the host's PCI bus, I can program the
inbound ATMUs such that the BARS are updated when the host (re-)scans
them, b
