Wade Fife 8ed69c7cdb fpga: rfnoc: Fix clock crossing in axis_data_to_chdr
This fixes some incorrectly handled clock crossings from axis_data_clk
to axis_chdr_clk, which could have manifested as timing failures (on
E320) or incorrect behavior, depending on the product and noc_shell
configuration.

Also cleans up trailing white space.

Wade Fife 59f5dcfc4f fpga: rfnoc: Add support for CHDR_W < ITEM_W*NIPC
This change fixes the case where CHDR_W < ITEM_W*NIPC.

It also adds a state machine to stall the input to the pyld_fifo to
ensure that the pkt_info_fifo will not overflow. Previously in some
cases it allowed the same word to be inserted into the pyld_fifo
multiple times.

Andrew Moch 55881469ac fpga: rfnoc: Add support for 512-bit CHDR widths
This fixes the rfnoc_null_src_sink, chdr_crossbar_nxn, and
chdr_stream_endpoint blocks so that wider CHDR widths are properly
supported. It also updates PkgChdrBfm to able to properly test these
blocks. The testbenches have been updated to test both 64 and 512-bit
widths.

Wade Fife 34d68cf4ca fpga: rfnoc: Add option to sample sideband info at start of packet
The axis_data_to_chdr block previously only sampled the sideband
information at the end of the packet. This adds a parameter that
controls if the sideband information should be sampled at the beginning
of the packet or the end of the packet. In the former case, large
internal packet buffers are not required.

+18 6b67702ad7 Merge FPGA repository back into UHD repository
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
