Ticket #2349
These commits enable the PPS API support in the master branch.
Two pointers to function were added in struct pps_state to replace dependencies
which are in rtems-libbsd (as was discussed in the mailing list, see
"Dependencies of PPS API in rtems-libsd").
For enabling the synchronization a configuration option was added (PPS_SYNC =
True).
It is still required some code, which should be implemented in a driver, for
getting the synchronization working.
Drivers that implement time synchronization through a PPS signal should have an
object of the type struct pps_state and call the functions pps_capture() and
pps_event().
Gabriel Moyano (12):
kern_ntptime.c: Disable freebsd features
kern_ntptime.c: Enable status variables when PPS_SYNC is defined
kern_ntptime.c: Add lmax() qmin() definitions
timepps: Add missing include for atomic type
kern_tc.c: Replace atomic functions required by PPS API
kern_tc.c: Replace FREEBSD event mechanism by adding pointers to
function
kern_tc.c: Remove verification of th_generation for pps functions
kern_tc.c: Add definition of tc_getfrequency in kern_tc
kern_tc.c: Add definitions required by PPS API
kern_tc.c: Enable PPS API support
kern_ntptime: Add define in order to remove warning
spec/build/cpukit: Add option for enabling PPS synchronization
