Hi,
When i mount device module such as ti_scm, usb via simplebus not nexus, i got an error:
*** LIBBSD MEDIA 1 TEST ***
nexus0: <RTEMS Nexus device>
ofwbus0: <Open Firmware Device Tree> on nexus0
simplebus0: <Flattened device tree simple bus> on ofwbus0
simplebus1: <Flattened device tree simple bus> on simplebus0
simplebus2: <Flattened device tree simple bus> mem 0x210000-0x211fff on simpleb1
ti_scm0: <TI Control Module> mem 0-0x7ff on simplebus2
ti_scm0: could not allocate resources
device_attach: ti_scm0 attach returned 6
I use gdb to debug it:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
(gdb)
It seems error came from using a resource that should be activated. the ofwbus_activate_resource is not exist.
So whether someone has been successful in porting a driver that uses simplebus in libbsd and that uses a resource that should be activated.
