The 4 parameters are added to facilitate transmiting project
related information to the software. They act as read-only
memory which is written in Vivado when the project builds.
Set 31 to SDI FIFO's almost full threshold
In case of multiple SDI (MISO) lanes, the samples arrives in a parallel
fashion. For example in case of 4 MISO line, at the first latching clock
edge 4 bits of a sample will be saved, one bit into each shift register.
The data reorder module reconstruct the incoming samples from the AXI
stream of the offload module.
Some IPs like JESD link layer were marked as not supported on Versal devices by
the current flow while other not (e.g. TPL).
The auto family support seems to workaround this issue.
This commit fixes an issue in situations where we provide an oversized
transaction to the data offload in TX mode. Previously, the data offload
would stop accepting new data (wr_ready <= 0) after filling up the
internal storage, and get stuck waiting for the input transaction to
end, thus locking up the device.
This commit addresses that issue by allowing the data offload to consume
the full input transaction, even if the tail of the buffer will be
truncated in the output.

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.

Add CMOS support for the interface for the following symbol modes on Xilinx devices:
A B C D E F G H
CSSI__1-lane 1 16/8 80(SDR)/160(DDR) 80 - SDR/DDR SDR/DDR->4/2(C=16), 2/1(C=8)
Columns description:
A - SSI Modes
B - Data Lanes Per Channel
C - Serialization factor Per data lane
D - Max data lane rate(MHz)
E - Max Clock rate (MHz)
F - Max Sample Rate for I/Q (MHz)
G - Data Type
H - DDS Rate
CSSI - CMOS Source Synchronous Interface
This commit changes the transfer length register to work in increments of
64 bytes and without offset. The true transfer length can now be
determined by multiplying the value of the transfer_length register with
64.
A value of zero is interpreted as a request for all available storage.
Additionally, this commit fixes an off by one issue that was discovered
during testing of the RX path.
