The predriver_hook entry in the RTEMS CPU Configuration
Table may be the address of a user provided routine that is
is invoked immediately before the the device drivers and MPCI

initialization is complete but interrupts and tasking are disabled.
This field may be NULL to indicate that the hook is not utilized.
Most BSPs do not use this callback.
