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.

White Rabbit is not supported in X410, however the register map included an
incorrect reference to this unsupported feature.
This commit removes the WR reference from both the source and html files.

Update rfnoc_image_core.v to take into account the new image_core_name

where needed.

This renames e31x_rfnoc_image_core.* to e310_rfnoc_image_core.*. This
makes the naming consistent with the rest of the build process (which
uses "e310" for all variants of e31x) and fixes an issue in which the
wrong file name was used by rfnoc_image_builder.

Add the Replay RFNoC block to the RFNoC core image for x300, x310, n300,
n310, n320/n321, and e320. The Replay block is contained within its own
static connection, so previous default behavior is still supported.

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 implements the same change that was made for E31x. The same issue
wasn't reproduced on N3xx, however this change keeps the code
consistent and eliminates the potential for the same problem.

Fixing an issue in which a very slow radio_clk (due to low sample clock
rate) could cause bus transactions to be issued to the timekeeper
faster than it could service them, resulting in a timeout. This change
replaces RegPort with CtrlPort so that proper flow control can be
maintained to the timekeeper.

It was set to E320_HG, which is not a valid target, causing build errors

Device was set to e31x, but this is not a valid device type. All e31x

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.

This updates the makefiles for the testbenches so they can be run using
"make modelsim" without any additional hacks. The "xsim" and "vsim"
simulation targets also still work.

Xilinx changed the way [all_registers -edge_triggered] is treated such
that set_max_delay constraints that use it can cause segmentation and
cause clocks to not be propagated to all endpoints. Changing to
[all_ffs] avoids this potential issue.

Adds a ZPU register to control the FP GPIO source. These are 2bits
per GPIO pin, totalling 24 bits. 0 corresponds to RF-A, 1 corresponds
to RF-B. The following Python code will control the upper 6 bits of the
front-panel GPIO from the B-side radio on an X300:
>>> import uhd
>>> U = uhd.usrp.MultiUSRP("type=x300")
>>> U.get_gpio_src_banks()
['FP0']
>>> U.get_gpio_src("FP0")
['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA',
'RFA', 'RFA']
>>> U.set_gpio_src("FP0", ['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA',
'RFB', 'RFB', 'RFB', 'RFB', 'RFB', 'RFB'])
>>> U.get_gpio_src("FP0")
['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFB', 'RFB', 'RFB', 'RFB',
'RFB', 'RFB']
>>> # Make all GPIOs outputs:
>>> U.set_gpio_attr("FP0A", "DDR", 0xFFF)
>>> U.set_gpio_attr("FP0B", "DDR", 0xFFF)
>>> # Control all GPIOs from software (not ATR):
>>> U.set_gpio_attr("FP0A", "CTRL", 0x000)
>>> U.set_gpio_attr("FP0B", "CTRL", 0x000)
>>> # Bottom 3 pins go high from radio A
>>> U.set_gpio_attr("FP0A", "OUT", 0x007)
>>> # Top 3 pins go high from radio B
>>> U.set_gpio_attr("FP0B", "OUT", 0xE00)
Amends the gpio.cpp example to allow switching the source.

Original-commit: d7304cc724de43b0d61d5b9d61a528d58898f004
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
