Common basic steps:
- Include/create infrastructure:
* Intel:
- require quartus::device package
- set_module_property VALIDATION_CALLBACK info_param_validate
* Xilinx
- add bd.tcl, containing init{} procedure. The init procedure will be
called when the IP will be instantiated into the block design.
- add to the xilinx_blockdiagram file group the bd.tcl and common_bd.tcl
- create GUI files
- add parameters in *_ip.tcl and *_hw.tcl (adi_add_auto_fpga_spec_params)
- add/propagate the info parameters through the IP verilog files

The ad_ip_jesd204_tpl_dac currently only supports JESD204 modes that have
both N and N' set to 16.
Newer DACs like the AD9172 support modes where N and N' are not equal to
16. Add support for these modes.
The width of the internal channel data path is set to N, only processing as
many bits as necessary. At the framer the data is up-sized to N' bits with
tail bits inserted as necessary. This data is then passed to the link
layer.
The width at the DMA interface is kept at 16 bits per sample regardless of
the configuration of either N or N'. This is done to keep the interface
consistent with the existing infrastructure it will connect to like upack
and DMA. The data is expected to the LSB aligned, the unused MSBs will be
ignored.
Same is true for the test-pattern data registers. These register keep their
existing 16-bit layout, but unused MSBs will be ignored by the core.
The PN generators are modified to create only N bits of data per sample.
Note that while the core can now support modes with N' = 12 there is still
the restriction that requires the number of frames per beat to be an even
number. Which means that not all modes with N' = 12 can be supported yet.

The current framer implementation is limited in that it only supports N'=16
and either S=1 or F=1.
Rework the framer implementation to be more flexible and support more
framer setting combinations.
The new framer implementation performs the mapping in two steps. First it
groups samples into frames, as there might be more than one frame per beat.
In the second step the frames are distributed onto the lanes.
Note that this still results in a single input bit being mapped onto a
single output bit and no combinatorial logic is involved. The two step
implementation just makes it (hopefully) easier to follow.
The only restriction that remains is that number of frames per beat must be
integer. This means that F must be either 1, 2 or 4. Supporting partial
frames would result in partial sample sets being consumed at the input,
which is not supported by input pipeline.
The new framer has provisions for handling values for the number of octets
per beat other than 4, but this is not exposed as a configuration option
yet since the link layer can only handle 4 octets per beat. Making the
octets per beat configurable is something for future iterations of the
core.

All parameters are DAC related since this is a peripheral that handles
DACs. Having DAC as a prefix on some of the parameter names is a bit
redundant, so remove them.

When the axi_ad9144 core is configured for DUAL mode two of the four
channels are unused. But there is still some residual logic left for those
unused channels that can't be removed by the optimizer.
Completely disable the unused channels by reducing the channel and lane
count. This slightly reduces utilization.

Replace the axi_ad9144 implementation with the new generic JESD204
interface DAC core. The replacement is functionally equivalent.

The DAC DMA will never overflow and unsurprisingly the dac_dovf signal is
never used anywhere. It is very unlikely it will ever be used, so remove
it.

The ADI transport layer peripherals expect the first octet to be in the
LSBs and the last octet to be in the MSBs. The Altera JESD204 core orders
the octets the other way around though, first octet in the MSBs and last
octet in the LSBS.
Currently this is handled by having each transport layer peripheral swap
the octets around when it is connected to the Altera JESD204 core.
Change this so that rather than having to do the data swizzling in every in
every transport layer peripheral perform it at the input/output of the link
layer peripheral inside the generated block.

The external s_axi_{awaddr,araddr} signals that are connect to the core
have their width set according to the specified size of the register map.
If the s_axi_{awaddr,araddr} signal of the core is wider (as it currently
is for many cores) the MSBs of those signals are left unconnected, which
generates a warning.
To avoid this make sure that the signal width matches the declared register
map size.

The width of a ternary operator expression is the width of the wider of the
two selectable expression. This means the right side expression of the
tx_data assigment is always 256 bits. This generates an implicit truncating
warning if the tx_data signal itself is only 128 bits.
To avoid this slightly reformulate the expression to yield the correct
width depending on the configuration.

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),

This is unused and unneeded. The AXI interconnect will make sure that a
peripheral only gets requests that are meant for it, there is no need to
check the address in the peripheral itself.
