- Fix NODE_INST
- Fix RFNOC_PROTOVER
- Add option to use SystemVerilog transport adapter for raw UDP
Original-commit: 693ec2c896306bcba3686385e5861593040d4cbd
This adds several features to the SystemVerilog Eth/IPv4/UDP transport
adaptor including:
- Compat register
- NODE_INST register
- Capabilities register
- KV map access for custom routing on RX data paths
- CHDR header removal for raw payloads to be sent over UDP
Also adds xport_adapter_ctrl.py, which allows controlling the new
registers.

Set the NODE_INST parameter for each transport adapter on X4xx so that
each adapter has a unique node instance number.
Original-commit: 8e87a4d24aeeb77a9528ff67a36d8a0ae12e7137
The NODE_INST parameter was set to 0. This adds it as a parameter so
that each transport adapter can have a unique node instance number.

The NET_CHDR_W parameter tells the transport adapter what CHDR width
is used in transport packets, such as Ethernet packets. By default the
CHDR width used by the transport and RFNoC core will be the same. The
NET_CHDR_W parameter can be used in situations where the RFNoC core
expects a CHDR width from the transport adapter that is different from
that used over the network. In this situation, the transport adapter
will rewrite the CHDR packets so that each side gets the expected CHDR
width.

Vivado has demonstrated difficulty meeting timing with the spi0_mosi split. To
improve the chances of meeting timing, we are routing this signal through a
BUFG. This makes the routing step use a more efficient net routing that eases
timing closure.

In Vivado 2021.1, it is no longer allowed to use "default: 0" to
initialize an enum within a packed struct. So we must initalize enum
data members explicitly now.

This fixes some issues with the 2021.1 version of the 10 GbE IP. In the
new version, link status is sporadically detected by the Xilinx IP when
nothing is connected to the port. Also, when the SFP is inserted, the
link status goes up and down multiple times. This change fixes this by
adding a counter and only considering it "linked" when the link has
been stable for some amount of time.

This adds the ability to do IP generation and FPGA builds using the
--jobs (-j) option with Make. For example, rather than generating each
IP one after another, you can generate up to N at a time using N Vivado
instances. This greatly reduces the IP generation time. Similarly,
parallel jobs can be used to easily build different FPGA variants
simultaneously.
Because FPGA builds can consume a lot of memory, care must be taken to
ensure that the number of jobs is not too high for the amount of memory
available.
New IP make targets were added for each USRP so that IP can be built
separately from the FPGA. The IP targets are now a dependency on each
FPGA target.
For example, you can generate the IP for X310 using 4 parallel jobs
using the following command:
make -j4 X310_IP
Or, build two X310 bitstreams simultaneously:
make -j2 X310_XG X310_HG

The main changes included are:
- Variant-dependent pin-out instantiation.
- Update clocking scheme in top level file
to include XO3 PLL

the GPIO communication interface with
the X410 FPGA.
- Include project files required to build
the XO3 variant of the ZBX CPLD.
- Add build flow for Lattice Diamond designs.
- Add ability to build XO3 variant of ZBX CPLD.

This fixes warnings regarding the first argument to $fatal(), which is
supposed to be a number indicating what diagnostics to display. 1
corresponds to "Prints simulation time and location".

This causes the latest RFNoC protocol version to be used by default
and avoids the need to update YAML files every time the RFNoC
protocol version gets bumped.
