The DC filter implementation in library/common/dc_filter.v is Xilinx
specific as it uses the Xilinx DSP48 hard-macro. There is a matching Altera
specific implementation in library/altera/common/dc_filter.v.
Move the Xilinx specific implementation from the generic common folder to
the Xilinx specific common folder in library/xilinx/common/ since that is
where all other Xilinx specific common modules reside.

Currently the IP component dependency in the Makefile system is the Vivado
project file. The project file is only a intermediary product in producing
the IP component definition file.
If building the component definition file fails or the process is aborted
half way through it is possible that the Vivado project file for the IP
component exists, but the IP component definition file does not.
In this case there will be no attempt to build the IP component definition
file when building a project that has a dependency on the IP component.
Building the project will fail in this case.
To avoid this update the Makefile rules so that the IP component definition
file is used as the dependency. In this case the IP component will be
re-build if the component definition file does not exist, even if the
project file exists.

At the moment targets are created for any file that is in a sub-directory
of the project directory. This is not the intended behavior. Targets should
only be generated for sub-projects. We can identify those by filtering for
sub-directories that have a Makefile.
E.g. some of those invalid targets were "adv7511.Makefile" and
"scripts.adi_board.tcl".

The project the help text uses as its example does no longer exist. Replace
it with a different project.

This reduces the amount of boilerplate code that is present in these
Makefiles by a lot.
It also makes it possible to update the Makefile rules in future without
having to re-generate all the Makefiles.

The library Makefiles for share most of their code. The only difference is
the list of project dependencies.
Create a file that has the common parts and can be included
by the library Makefiles.
This drastically reduces the size of the library Makefiles and also allows
to change the Makefile implementation without having to re-generate all
Makefiles.

Removes a lot of boilerplate code.
Using the new scheme it is possible to add new projects or sub-projects
without having to re-generate any existing Makefiles.

The project top-level Makefile accept the all, clean and clean-all targets
and forward them to their sub-projects.
Create a common Makefile include that can be used to implement this
behavior. The shared Makefile collects all sub-directories that have a
Makefile and then forwards the all, clean and clean-all targets to them.
This is implemented by creating virtual targets for each combination of
sub-project and all, clean, clean-all targets in the form of
"$project/all", ... These virtual sub-targets are then listed as the
prerequisites of the project top-level Makefile targets.
This means there is no longer a need to re-generate top-level Makefiles
when a new project or sub-project is added.
It will also allow to remove a lot of boilerplate code.

The TX side runs on QPLL, and the RX and RX_OS runs on CPLL by default.
The OUTCLK frequency is the same as the REFCLK.
The main reason of this modification is that the links should come up
without any DPR access, after power up, using the default reference clock
configuration (122.88 MHz).
This way the user do not need to modify the block design, just
set the required rate in system_bd.tcl.
This commit does not contain any functional changes.
In cases when a shallow FIFO is requested the synthesizer infers distributed RAM
instead of block RAMs. This can be an issue when the clocks of the FIFO are
asynchronous since a timing path is created though the LUTs which implement the
memory, resulting in timing failures. Ignoring timing through the path is not a
solution since would lead to metastability.
This does not happens with block RAMs.
The solution is to use the ad_mem (block RAM) in case of async clocks and letting
the synthesizer do it's job in case of sync clocks for optimal resource utilization.
Add a parameter to the control the clock source option of the MMCM. If
the MMCM has only one clock source the CLKSEL pin will be tied to VDD.
The previous version added a redundant path between the CLKSEL port and
register map.
Explicitly select MIO 52 and 53 pins to be part of MDIO port.
MIO_52_PIN (MDIO 0 Clock, Output)
MIO_53_PIN (MDIO 0 Data, Input/Output)
After the tool version change, this pins where by default connected
as MIO GPIOs.
