This line controls the mux, which switch between hdl and software (GPIO) control of the ENABLE/TXNRX pins.
Fix the broken path and change the name from "tdd_enable" to "tdd_enabled".
Supported carrier are ZC706 and RFSOM.
The synchronization pulse is automatically generated by the master terminal, when TDD mode is enabled.
By default a terminal is slave, software must write 0x01 into TDD register 0x50.
Add .gitattributes file which sets up the eol encoding handling. This will
make sure that we get a uniform eol encoding across different operating
systems.

On ZYNQ the HP interconnects have a AXI3 interface. The DMA controller
supports both AXI4 and AXI3. By switching to AXI3 there is no need to create
a protocol converter between the DMA and the HP port.

The AXI master interface and the register map AXI slave interface use the
same clock. No need to mark the interfaces as asynchronous. This removes the
need for CDC logic on those paths.

The DMA controller is able to send AXI3 compatible requests, no need to add
a interconnect for protocol conversion in between the DMA controller and the
HP port.

There are only 4 DAC channels in the fmcomms2 design, so set the number of
channels of the dac_unpack core to 4. This slightly reduces resource usage
as well as reducing the DMA alignment requirement from 128bit to 64bit. The
later value is what existing applications expect the alignement requirement
to be.

ZC706 runs rx_clk at 250 MHz.
ZC702 and ZED run rx_clk at 200 MHz due to slower fabric.
The ZC702 and ZED projects need init_user in the boot procedure in order for the HP Ports to work correctly.
Both DDS and DMA mode work.
