This file is the RTEMS implementation of ofw_if.h in FreeBSD. The ofw_if.h in FreeBSD is an autogenerated header file that maps the OF_function calls to their respective implementation. But in RTEMS this file maps the OF_functions directly to their FDT implementation. --- bsps/shared/freebsd/dev/ofw/ofw_if.h | 63 ++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 bsps/shared/freebsd/dev/ofw/ofw_if.h
