Istvan Csomortani b2d86bab47 util_axis_fifo: Fix the FIFO level generation in ASYNC mode
The FIFO functions in 'first fall through' mode, adjust the fifo level
generation so it take into account the valid data which sits on the bus,
waiting for ready, too.

Lars-Peter Clausen d72fac4b1e Add missing timescale annotations
For consistent simulation behavior it is recommended to annotate all source
files with a timescale. Add it to those where it is currently missing.

Lars-Peter Clausen 2b914d33c1 Move Altera IP core dependency tracking to library Makefiles
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.

Lars-Peter Clausen 35a39ba2e6 Regenerate library Makefiles using the new shared Makefile include
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.

Laszlo Nagy bfc8ec28c3 util_axis_fifo: instantiate block ram in async mode
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.

Lars-Peter Clausen e644a99648 util_axis_fifo: Fix some data width mismatches
Make sure that the right hand side expression of assignments is not wider
than the target signal. This avoids warnings about implicit truncations.

None of these changes affect the behaviour, just fixes some warnings about
implicit signal truncation.

Istvan Csomortani 9055774795 all: Update license for all hdl source files
All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.

New license looks as follows:

Lars-Peter Clausen a0e30a2211 util_axis_fifo: Improve clock gating of registers and BRAM
Currently the BRAM and data registers in the util_axis_data are ungated
when the FIFO is ready to receive data. This good for high-performance
since it reduces the number of control signals. But it is bad from a power
point of view since it causes additional reads and writes.

Change the core gate the BRAM and data register if either the consumer is
not ready to accept data or the producer has no data to offer.

Adrian Costina dc2b37bd0c Makefile: Added top level Makefile. Modified behavior of clean and clean-all
Clean ran for a project will clean only the project files.
Clean-all ran for a project will clean also the library files on which the project depends.
The clean commands will only remove specific files and directories.

The top Makefile allows several options(per suggestion from jameyhicks):
make fmcomms1.zed will run "make all" in projects/fmcomms1/zed/
make clean will run "make clean" for all the projects
make clean-all will run "make clean" for all the projects and libraries
make lib will run "make all" for the library files
