Typically any Freescale PCI-X bridge hardware strapped into Agent mode is
58+
prevented from enumerating the bus. The PrPMC form-factor requires all
59+
mezzanines to be PCI-X Agents, but one per system may still enumerate the
60+
bus.

This property allows a PCI-X bridge to be used for bus enumeration

despite being strapped into Agent mode.

description:
13+
Define a generic node representing a PCI endpoint which contains several sub-
14+
peripherals. The peripherals can be accessed through one or more BARs.

16+
does not represent a device tree binding by itself.

description:

One node for each BAR used by peripherals contained in the PCI endpoint.
41+
Each node represents a bus on which peripherals are connected.
42+
This allows for some segmentation, e.g., one peripheral is accessible
43+
through BAR0 and another through BAR1, and you don't want the two
44+
peripherals to be able to act on the other BAR. Alternatively, when
45+
different peripherals need to share BARs, you can define only one node
46+
and use a 'ranges' property to map all the used BARs.
