This is a straight and complete copy of sdbfs/lib from the
fpga-config-space project (ohwr.org).  The last sdbfs commit in there
as I pick this is d37e888.

Further commits in sdb-lib within wrpc-sw are expected to exactly
track fpga-config-space (and report the upstream commit), to avoid
maintainance issues.  However, I prefer not to have a submodule since
it makes things difficult for such a small code subset.

When WR PTP Core is set in GrandMaster mode it aligns its nanosecond
counter to 1-PPS and 10MHz coming from external source. When user wants
to set seconds counter to a desired value (with _time set_ command), the
nanosecond counter was also set (zeroed) causing additional (random)
offset to the external source. The commit adds _time setsec_ and _time
setnsec_ for setting only seconds or nanoseconds counter without
affecting the other one. Now, when user wants to set current time on a
GrandMaster Node he has to call _time setsec_ command after _mode gm_

traffic has to go into external fabric interface of WRPC because it won't be

We don't want to call the real printf, which brings in the whole of
newlib, but it sometimes happen. So let's diagnose the problem
immediately rather than letting users wonder what is wrong with the
size.

Similarly, if building under ppsi, ensure we are not calling libgcc
division functions: any 64-bit division my be done with __div64_32
offered by ppsi/lib (copied from the kernel).

This reverts commit 0bcbe429.

Now that we are able to check for bogus printf calls, don't define the
name any more (ptp-noposix defines it anyways, but let's not do it
when building with ppsi, so the code explicitly calls pp_printf (or
mprintf, which will remain as an alias until we get rid of
ptp-noposix).

This reads to stdout, in binary format. With "-v" it prints text and
scans the bus too. The examples here below use the same card (and same

The command is not documented, and it looks like is not useful either
