Some of the standard Quartus components (especially the Merlin cores) generate
quite a few synthesis warnings. Lets assume these are false positives and
disable the warnings.

Add a parameter to the ad_xcvrcon function that allows to provide a mapping
between logical and physical lanes. By default if no lane map is provided
the logial and physical lanes are mapped 1-to-1. If a lane map is provided
logical lane $n is mapped onto physical lane $lane_map[$n].

Let the ad_xcvrcon handle the ADI JESD204 link layer cores. The function
will detect the JESD204 core vendor and connect the appropriate signals
based on it. This means it can still be used with the Xilinx JESD204 core
as well.

When trying to use ad_cpu_interconnect to connect to a AXI interface that
is a outer port of a hierarchy this will fail at the moment as it kind find
the matching clock and reset signals.
Add support for traversing into the hierarchy and find the final target AXI
port inside the hierarchy. Then find the matching clock and reset and
traverse them back the corresponding hierarchy outer ports.

In case of axi_interconnects, when just one slave and master interface is
active, the 'Interconnect Optimization Strategy' is disabled. So this
parameter should be set just if there is more than one slave interface.
Only enable bitstream compression only if both the
ADI_NO_BITSTREAM_COMPRESSION environment and TCL variable are not set.

Enabling bitstream compression reduces the size of the generated bitstream.
This means on one hand it will consume less storage, which is especially
useful for the BOOT partition of the ADI images where we store BOOT.BIN
files for all supported platforms.
On the other hand a smaller bitstream is faster to load from the storage
medium and it is also faster to program to the FPGA. So it reduces the
overall boot time as well.
The only downside of bitstream compression is that the bitstream size is no
longer constant, but depends on the actual design and resource utilization.
This will not work with bootloaders that expect a fixed size.
When building a bitstream using the tcl scripts bitstream compression can
be disabled by setting the ADI_NO_BITSTREAM_COMPRESSION environment
variable.
Initial tests show a reduction of a round 50% in size for most ADI
projects.

Property 'board' is deprecated for object type 'project', 'board_part' is used. Update the 'board_part' property names for all Xilinx development boards.
Add .gitattributes file which sets up the eol encoding handling. This will
make sure that we get a uniform eol encoding across different operating
systems.

Sometimes the find_bd_objs does not do its job, so need to double check that the interface clock is already connected to the p_clock or not.
Not sure about the cause of this behavior, need more investigation. Issue was found first at KC705 base design.
The scripts generating the projects files typically only work correctly with
one specific version of Vivado. If a incorrect version is used the script
may fail at some point with a cryptic error message or may not fail but
create a bitstream that is not working as expected, e.g. unconnected
signals, etc. This patch adds a version check to adi_project_create that
will error out early on stating that the wrong version of Vivado was used
and which is the right version to use.
By default the required version will be the version that is required by the
common scripts. Individual projects can overwrite the required version by
setting the REQUIRED_VIVADO_VERSION variable to the required version or can
bypass the version check completely by setting the IGNORE_VERSION_CHECK
variable to 1.
Callers of the script can also disable the version check by setting the
ADI_IGNORE_VERSION_CHECK environment variable.

In 2014.2 tool version, the way how a definition file needs to be applied is different
The command "apply_bd_automation" should be used, instead setting property PCW_IMPORT_BOARD_PRESET
In non-project mode (PR design flow), after creating the static design the type of the board is set.
NOTE: the definition file for mitx must be installed accordingly in order to get this work
See link: http://zedboard.org/support/documentation/2056
+ Rewrite the pr_verify process, to improve verification time
+ Update the implementation flow: always the biggest logic will be implemented first, to achieve a better result
therefore force the tool to optimize the first logic with 'ExploreSequentialArea'
+ Make utilization report just from the PR pblock, that's more relevant as the utilization report of the whole fabric
- Change implementation strategy to Performance Explore.
At some projects, this could prevent timing issues, it not
increase the overall implementation time in a dramatic way.
The FMCOMMS1 meets timing on ZED/ZC702 only if the phys_opt_design step
is part of the implmentation flow, with the Explore argument.
"This step performs physical optimizations such as timing-driven
replicaiton of high fanouts nets to improve timing results"
