Deprecate unused parameters.
Change to MEM_SIZE_LOG2, to support only power of 2 storage sizes for
now. However in the future we might want to add support for non pow2
sizes so register map is not changed.
Change transfer length to -1 value to spare logic.
Change FIFO interface to AXIS to have backpressure, this allows the
implementation of data movement logic in the storage unit and let the
FSM handle high level control an synchronization and control the storage
unit through a control interface.
Refactor FSM to have preparation states where slow storages can be
configured and started ahead of the data handling.
Make bypasss FIFO optional since in some cases causes timing failures
due the missing output register of the memory. This can be targeted in
a later commit.
Hook up underflow/overflow to regmap useful in case of external memory
where rate drops due misconfiguration can be detected.
Cleanup for verilator.
Scripting:
Add HBM and DDR external memory support using util_hbm IP
Replace asym_block_ram with util_do_ram IP
This commit adds a new synthesis option to the design, that controls
whether an internal clock domain crossing will be generated. Disabling
this option allows you to use a synchronization signal that is
synchronized to the write clock domain externally, and possibly shared
between multiple devices.
The default value retains the old behavior.

Create the dacfifo/adcfifo infrastructure with procedures.
This will allow moving the parameters of the dac/adcfifo inside
the block design so it can be calculated based on other parameters.
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.

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.
