729ce58f98 sayma: use GTP_CLK1 to clock DRTIO satellite transceiver
This is required to get constant skew between the DRTIO transceiver clock
(which then generates the RTIO clock) and the siphaser reference clock.

Both the Si5324 and the RTM clock tree have non-deterministic in-to-out skew
at 150MHz due to dividers.

a65721d649 sayma: put RTM clock tree into the siphaser loop
* Fixes one bug where siphaser was one Si5324 output and the rest of the
system was clocked by the other. With the Si5324 settings we have, skew
between the outputs is not controlled.
* Puts the coaxial cable between AMC and RTM into the siphaser loop.

Added comment to clarify that ``artiq-main`` is the conda environment.

5e5cdf0e67 Update installing.rst
The file 99-openocd.rules as downloaded from githubusercontent.com seems to be outdated and does now work on Ubuntu 16.04. The version that ships with OpenOCD has an additional ``TAG+="uaccess"`` in the rules file and works fine. Thus I suggest to use the file that is bundled with OpenOCD.

68530fde07 sayma: generate 100MHz from Si5324 on standalone and master targets
* Allow switching between DRTIO satellite and standalone without

* Allow operating standalone and master without an additional RF
  signal generator.

0c32d07e8b ad9154: new sysref scan
Print margins around the pre-defined fixed phase.
Also report error if margins are too small.

The fixed phase is also changed by this commit (the value 88 is
from before the new HMC7043 initialization code, and is probably wrong).
