Adds a 266.667 MHz compute engine clock and uses it instead of the
radio clock for the DDC and DUC. Using a faster clock than the radio
allows the DDC and DUC to drain after a stall in the data flow.

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.

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

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.

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.

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

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.

The FSRU (aka EISCAT) was never supported in UHD 4.0. The FPGA
repository never had the relevant files, and the block controller also
never existed. This removes all the corresponding files from MPM, as
well as some references from makefiles.

This sets the ARCH and PART_ID environment variables so that the
selected part family is used for simulations by default. This can be
overridden by changing them in the Makefile for the testbench if a
testbench requires a specific part family. Prior to this change, the
default was always ARCH=kintex7, PART_ID=xc7k410t/ffg900/-2, which
required support for that part to be installed.

Add the Replay RFNoC block to the RFNoC core image for x300, x310, n300,

This updates the IO signatures so that all devices and RFNoC blocks use
the same IO signature for the DRAM. This is needed because the IO
signatures must match between the RFNoC blocks and the devices. This
means that some devices have extra bits in the IO signature for the
address, but the extra bits will simply be ignored.

This adds new image files which come with a DRAM FIFO. The addition of
an N320 image with a DRAM FIFO allows DDR3 BIST to be run on an
assembled (motherboard + daughterboard) N320.
This image is intentionally very similar to the N300_AA and N310_AA
targets which serve the same purpose of providing an image with a DRAM
FIFO for their respective devices.

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
