When the DMAC is used in async clock domains the data FIFO instantiate
an ad_mem component to handle properly the clock crossing.
For Intel, this mode is used only in FMCJESDADC1 designs but without this
an error could appear in other projects too if the user reconfigures the core.
The set_false_path constraint targeted to the *ram* cells of the dmac
matched several intra clock domain paths where the timing analysis got
ignored resulting in intermitent data integrity issues.
Exposed AXI3 interface on the Intel version of the IP for UI and feature consistency.
Some of the signals that are defined as optional in the AMBA standard
are marked as mandatory in Qsys in case of AXI3. Because of this such signals
were added to the interface of the DMAC and driven with default values.
For Xilinx in order to keep existing behavior the newly added signals
are hidden from the interface.
New parameters are added to define the width of the AXI transaction IDs;
these are hidden from the UI; We can add them to the UI if the fixed size
of the IDs will cause port incompatibility issues.

Not all echo implementations support escape characters and newline
insertion. Make sure quiet.mk does not use escape characters to generate
newlines and instead split the output over multiple echo commands to get
the same effect.

All the file names must have the same name as its module. Change all the
files, which did not respect this rule.
Update all the make files and Tcl scripts.
Most of the cores are fully covered by the generic constraint files. When
the constraints where moved from the core specific to the generic
constraint files some empty core constraints files where left around. These
don't do anything, so remove them.

The standard Makefile output is very noisy and it can be difficult to
filter the interesting information from this noise.
In quiet mode the standard Makefile output will be suppressed and instead a
short human readable description of the current task is shown.
E.g.
> make adv7511.zed
Building axi_clkgen library [library/axi_clkgen/axi_clkgen_ip.log] ... OK
Building axi_hdmi_tx library [library/axi_hdmi_tx/axi_hdmi_tx_ip.log] ... OK
Building axi_i2s_adi library [library/axi_i2s_adi/axi_i2s_adi_ip.log] ... OK
Building axi_spdif_tx library [library/axi_spdif_tx/axi_spdif_tx_ip.log] ... OK
Building util_i2c_mixer library [library/util_i2c_mixer/util_i2c_mixer_ip.log] ... OK
Building adv7511_zed project [projects/adv7511/zed/adv7511_zed_vivado.log] ... OK
Quiet mode is enabled by default since it generates a more human readable
output. It can be disabled by passing VERBOSE=1 to make or setting the
VERBOSE environment variable to 1 before calling make.
E.g.
> make adv7511.zed VERBOSE=1
make[1]: Entering directory 'library/axi_clkgen'
rm -rf *.cache *.data *.xpr *.log component.xml *.jou xgui
*.ip_user_files *.srcs *.hw *.sim .Xil .timestamp_altera

Currently the individual IP core dependencies are tracked inside the
library Makefile for Xilinx IPs and the project Makefiles only reference
the IP cores.
For Altera on the other hand the individual dependencies are tracked inside
the project Makefile. This leads to a lot of duplicated lists and also
means that the project Makefiles need to be regenerated when one of the IP
cores changes their files.
Change the Altera projects to a similar scheme than the Xilinx projects.
The projects themselves only reference the library as a whole as their
dependency while the library Makefile references the individual source
dependencies.
Since on Altera there is no target that has to be generated create a dummy
target called ".timestamp_altera" who's only purpose is to have a timestamp
that is greater or equal to the timestamp of all of the IP core files. This
means the project Makefile can have a dependency on this file and make sure
that the project will be rebuild if any of the files in the library
changes.
This patch contains quite a bit of churn, but hopefully it reduces the
amount of churn in the future when modifying Altera IP cores.

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".

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

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.
