Because the golden bitstream for SPEC has syscon at offset 0x0.

E.g. Kintex-7

Based on Peter's work for km2net CLB board.

Reason: h_y was close to the DAC range, on some boards we were unable to lock
HPLL.
In addition to HPLL modifications, also the phase shifting had to be changed.
When offset clock has lower frequency than the ref clock, shifting ref
clock produces sampled clock which is shifted in another direction.

The function ptpd_netif_create_socket() still receives two arguments,
because it is being called by ppsi, and I'd better not change the API
in small steps in there.

The function are not there:

 * ptpd_netif_poll()
      it never existed

 * ptpd_netif_select()
      nobody called it, and it only returned 0

 * ptpd_netif_locking_enable()
 * ptpd_netif_locking_disable()
 * ptpd_netif_locking_poll()
 * ptpd_netif_adjust_counters()
 * ptpd_netif_adjust_phase()
 * ptpd_netif_adjust_in_progress()
 * ptpd_netif_enable_timing_output()
 * ptpd_netif_enable_phase_tracking()
 * ptpd_netif_read_calibration_data()
      they were part of ptp-noposix-wrappers.c, removed in January 2015.
      The features are now part of the wr_ops in ppsi.

 * ptpd_netif_get_ifName()
      same (ptp-noposix-wrappers.c), it returned a constant name, and
      ppsi does it differently because based on arch-wrs/arch-wrpc

 * ptpd_netif_calibrating_enable()
 * ptpd_netif_calibrating_disable()
 * ptpd_netif_extsrc_detection()
      same, but in addition they were already doing nothing when removed

 * ptpd_netif_calibrating_poll()
 * ptpd_netif_calibration_pattern_enable()
 * ptpd_netif_calibration_pattern_disable()
      same, but they wer not actually used since calibration was gone

This time I added -Wmissing-prototypes and fixed accordingly. Again, this
used to be part of -Wall and I'm disgusted by it not being so any more.

What does "all" mean, then?

Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

I added -Wstrict-prototypes, that used to be included in -Wall settings
but is not.  Actually, I think it should be an error to not specify an
argument list by now.  If any, -traditional is there for old timers.

Fortunately no bug was exposed by the missing prototypes.

This adds two commands: devemem (to read and write registers/RAM)
and delays (to read and change the constant delays.  The commands are
only available for CONFIG_DEVELOPER builds.

The default delays were just wrong, they are valid of an older
gateware version.  Using 0, it is clearer to the user that the right
value is missing (if the SFP database is populated, the right value
applies anyways).

Add checking stack overflow and detecting reset to wrs. Code common for wrpc
and wrs is placed in system_checks.c and .h. Work is based on following
commits in wrc_main.c:
1704a668 main: check for stack overflow
7836c39e

 Optionally detect reset and print a stack trace

Additionally:
--update Kconfig to have a possibility to select CHECK_RESET also for switch,
  not only for node as before
--and _endram to ram-wrs.ld

When "stack overflow" occurs then message is printed once every second.
When reset occours then LM32 will print stack trace and reset once more.
NOTE: I couldn't get spll to work after reset, for sure problem is in
      ad9516 init function, but not only there.

ppsi for wrs requres locks in shmem when shmem is changing. Since servo is
shared between wrs and wrpc fixes had to be implemented.
Since there is no shmem in wrpc, dummy function for locking had to be added.
As a side effect include/libwr/shmem.h was added.

This is useful for example when using a secondary onewire controller.

This reverts commit 7e2ee9b4.

You can't put a bitstream into the middle of a tiny EEPROM.
If you intend to build an sdbfs for a switch, make a new image.
