- All RFNoC capable targets now require rfnoc_image_builder to be built
- `make help` is updated for all targets to provide more useful and
up-to-date information
- The FPGA manual is also updated
- All checked-in build artifacts are now removed from git
- axi_ram_fifo.yml is updated to provide include path information
(required for building N3xx BIST images, which use this)

Most important effect of this change: rfnoc_image_builder is now
required to build bitfiles, 'make' alone won't suffice any longer!
This is a huge changeset to the image builder that combines multiple new
features:
- There no longer is a separate edge file for the static router. The
static routes are generated as a Verilog parameter directly into the
rfnoc_core_kernel (which is also modified).
- image_builder.py is split up into several smaller files. Code is moved
into yaml_utils.py, and the new files grc.py, builder_config.py
- Generic module support is added. Aside from noc blocks and stream
endpoints, we can now instantiate arbitrary modules (they also require
a YAML description file).
- To enable such modules, resets are now also tracked the same way that
clock domains are.
- The ImageBuilderConfig config object now more closes matches the
original YAML file. The attributes 'clk_domain_con' and 'block_con' are
removed. Instead, the attributes 'connections' and 'clk_domains' are
sanitized and amended with extra annotations. The templates are
updated to reflect this change.
- IO ports can now carry parameters, e.g., to have variable wire widths
based on the configuration.
- Many Pylint warnings were resolved.
- Add inheritance support for image core YAML files.
This allows image core files to (recursively) inherit from other image
core files. To do so, simply put an 'inherit' entry at the top of the
file:
```yaml
inherit: 'x410_radio_base.yml'
```
- The inheritance feature is used as part of the image core files.
- Image core and DTS files are now generated as a build artefact into
the build directory. This requires the usage of rfnoc_image_builder to
build images. As a consequence, it is no longer required to check in
image core Verilog files.
- As another consequence, rfnoc_image_builder is required to build
bitfiles!
- Image flavours are no longer defined through Makefiles, but purely
from the image core YAML files.
- Remove all image core YAML files that do not generate a shipping
image. Because of the inheritance feature and the requirement to use
the image builder, it is trivial to add new YAML files.
- Add support for transport adapters through the YAML files. Before,
transport adapters were inferred from the make target (e.g.,
X410_X4_200 would have four 10GbE links based on the 'X4' substring).
Now, transport adapters are defined via the image core YAML.
- This feature is currently only used (or can be used) by the X4xx
series. Older devices may or may not be ported to allow custom
transport adapters in the future.
- Add parameters to the BSP YAMLs and the devices itself. This allows
setting global parameters in the image core files. For example, the
X4x0 devices use this to decide if they instantiate DRAM channels.
- DTS includes and constraint files can now be requested by
blocks/transport adapter through their YAML files. They do no longer
need to be listed in the Makefile.
- Support for secure image cores. These are image cores that allow
incorporating RFNoC blocks that require license keys and thus can't
live in an open-source environment. This solution adds the option for
secure image cores without touching the open source feature set.
- Add --reuse option to allow manual editing of generated artefacts
- Allow IO signatures from any module: until now IO signatures had to be
defined in a single file (io_signatures). This file will persist. In
addition each module can add its own IO signature as with the same
format the core IO signatures placed under the top level key
`io_signatures`. IO signatures are still maintained in a global
dictionary. The consequence is that they can be shared among
independent modules as well as they have to have a globally unique
name. The image builder will warn about detected name clashes for the
signatures.
- As a consequence, some less commonly used IO signatures were moved to
their corresponding module YAML files.

In the build Makefiles, this adds a function (uniq) which removes
duplicate entries from lists. We apply this to the DESIGN_SRCS passed
to the Vivado build process. This eliminates some warnings from
duplicate source files caused by redundantly referencing source files in
the Makefiles, possibly because they are listed in more than one source
file variable.

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

- 2to3 was used to convert the Python scripts, except where the tool
choked and manual intervention was required
- All references to "python" where replaced with "python3"
- buffer() was replaced by memoryview()

The FPGA codebase was removed from the UHD repository in 2014 to reduce
the size of the repository. However, over the last half-decade, the
split between the repositories has proven more burdensome than it has
been helpful. By merging the FPGA code back, it will be possible to
create atomic commits that touch both FPGA and UHD codebases. Continuous
integration testing is also simplified by merging the repositories,
because it was previously difficult to automatically derive the correct
UHD branch when testing a feature branch on the FPGA repository.
This commit also updates the license files and paths therein.
We are therefore merging the repositories again. Future development for
FPGA code will happen in the same repository as the UHD host code and
MPM code.
== Original Codebase and Rebasing ==
The original FPGA repository will be hosted for the foreseeable future
at its original local location: https://github.com/EttusResearch/fpga/
It can be used for bisecting, reference, and a more detailed history.
The final commit from said repository to be merged here is
05003794e2da61cabf64dd278c45685a7abad7ec. This commit is tagged as
v4.0.0.0-pre-uhd-merge.
If you have changes in the FPGA repository that you want to rebase onto
the UHD repository, simply run the following commands:
- Create a directory to store patches (this should be an empty
directory):
mkdir ~/patches
- Now make sure that your FPGA codebase is based on the same state as
the code that was merged:
cd src/fpga # Or wherever your FPGA code is stored
git rebase v4.0.0.0-pre-uhd-merge
Note: The rebase command may look slightly different depending on what
exactly you're trying to rebase.
- Create a patch set for your changes versus v4.0.0.0-pre-uhd-merge:
git format-patch v4.0.0.0-pre-uhd-merge -o ~/patches
Note: Make sure that only patches are stored in your output directory.
It should otherwise be empty. Make sure that you picked the correct
range of commits, and only commits you wanted to rebase were exported
as patch files.
- Go to the UHD repository and apply the patches:
cd src/uhd # Or wherever your UHD repository is stored
git am --directory fpga ~/patches/*
rm -rf ~/patches # This is for cleanup
