Fix the TUSER width for some buses in eth_ipv4_chdr_adapter. This
allows wider CHDR widths to be used with 10 GbE.

FPGA:
- Split up MB registers that control daughterboard specific settings so
that daughterboards 0 and 1 could have different setings, in
preparation for future devices that require different settings.
This requires a compat number bump to 8.0.
- Add registers for additional RFDC information, including the
block/tile mapping of the individual channels, and information about
resampling capabilities
- Identify sections of code that would be specific to X410/ZBX and move
them to their own headers, so it's trivial to add device-specific
sections of code instead for other devices in the future.
- This includes constraints for clocks and I/O pins.
- Remove ability to do timed ctrlport transactions to the MB CPLD, this
was unused and possibly broken.
- Move daughterboard-specific code into its own code location
(dboards/zbx)
- Move X410-specific register documentation to its own location
(doc/X410)
- Refactor Makefiles to split out X410/ZBX specific components and allow
switching between device types
- Add 512-bit AXI interconnects
- Make number of timekeepers configurable (X410 keeps the single
timekeeper)
MPM:
- Required compat is bumped to 8.0
- Now supports new registers for detecting DSP capabilities and
multi-rate settings for the daughterboards
- Adds MMCM controls (currently unused)

The frontend synchronization upon time change was removed, but is
required to synchronize the RX frontend modules when sharing LOs on
TwinRX. This change restores the behavior.

The time changed signal was removed and is needed to synchronized the
frontend. This restores the signal.

Gaps in transmission were seen when using the replay buffered TX
streamer caused by the Replay block setting the end of burst flag at the
end of every send() call. This fix adds a flag to the Replay block play
command register to avoid setting the end of burst flag and modifies the
replay buffered TX streamer to use the flag based on the metadata passed
in to the send() call.

Module description:
Clock divider. Generates an output clock that is 1/N times the
frequency of the input clock.

Moves X4C_100, X4C_200, C1_100, and C1_200 from experimental to
available targets and makes the needed changes to allow them to build
successfully.
Adds support for "UC" FPGA variant. U indicates that QSFP0 is unused
and C indicates that QSFP1 is 100 GbE.
Adds experimental CG_200 variant.

Removes the CPU_W parameter from x4xx.v and the qsfp_wrapper files. The
value of this parameter depends on the axi_eth_dma IP and therefore
should not be changed.

This means that the stream endpoint's crossbar connection can be wider
and therefore support a higher bandwidth than the RFNoC block to which
the endpoint is connected. This improves host streaming performance.

Both the chdr_stream_output and chdr_xb_ingress_buff have a packet
gate, making one of them somewhat redundant. Removing one of them
reduces latency and frees up FPGA resources.
Original-commit: 9533bd025d74787d25b135d3092bffa1b51f6731
This adds a parameter to chdr_xb_ingress_buff and to chdr_stream_output
to make their packet gates optional. They are included by default.
Having the packet gate in chdr_xb_ingress_buff can reduce contention in
the crossbar. Having the packet gate in chdr_stream_output can reduce
the latency for non-data packets (e.g., stream status updates).

This adds support for different widths on each port and adds the
ability to disable routes within the crossbar. Both of these features
allow for FPGA resource savings.
These features are controlled by the new parameters PORT_WIDTHS and
ENABLED_PATHS. Unused routes will have the associated logic removed.
A new testbench adds support for testing different port widths and
disabled routes. It also adds more rigrous testing of the crossbar.

The long lines were causing Debian lintian failures, so they have been

Adds a BUILD_BASE_DIR makefile variable that allows you to specify the
base directory for FPGA build outputs. This allows you to put the
output from each run of make into a unique directory, or to run
multiple instances of make in parallel with each build's output being
put in a different directory. For example:
make X310_XG BUILD_BASE_DIR=/path/to/builds
Original-commit: bc6db8409ba756bbad0d0c158ffb00c614b58fd9
Adds a BUILD_SEED make variable that can be set to a 32-bit integer,
and adds an FPGA read-only register initialized by this variable.
Changing this variable will randomly affect the FPGA build results.
This can be useful when your build fails timing by a small amount,
allowing you to build again and get different results with the same
code.
For example, you could run the following to produce an FPGA build with
different timing results from the default build:
make X310_XG BUILD_SEED=123

The FIR filter applied gain. Removing it caused incorrect scaling and
signals where every other sample was zero. Also parameterized heterodyne
frontend processing so it would not use resources in images not
requiring it.
