I wonder why this never came up with Zynq or QorIQ. Maybe no one wanted
to run network tests on the alternate interfaces because dev boards with
those interfaces configured didn't exist? It's possible that the ukphy
driver could be improved and this entire problem just goes away or we
ban that driver from the default configuration for multi-interface BSPs
and the problem goes away.
The QorIQ BSP uses a device tree.
The chips will get more and more complex. Managing this complexity with
hand written C preprocessor defines is a dead end from my point of view.
Device trees allow you to provide a generic BSP which is initialized for
a particular board using the device tree. Compared to other operating
systems, the device tree support and generic device enumeration in RTEMS
is a bit under developed. See for example:
