The 2^18 dma address width with a 64 dma data width will result a FIFO, what will be implemented by 512 RAMB36 cells.
This is a the maximum BRAM FIFO depth in case of the VC707.
The paths from the HDMI interface registers to the IO pads are
unconstrained. This means the P&R can in theory put the register anywhere
which could lead to stability issues on the interface, depending on what
else is in the fabric. To get predictable delays for the register to IO pad
path place the register into the IOB section.

The HP memory ports on ZYNQ are AXI3. The AXI-DMAC supports both native AXI3
and AXI4, by configuring it for AXI3 there is no need for a protocol
converter inside the interconnect, that connects the DMAC to the HP port.
In addition to that also set the data width for the DMAC on the HP port side
to 64 so there is no need for a memory width converter in the interconnect.

The toplevel input/output signal names are lower case, but the signals
connected to the system_wrapper are upper case. Since verilog is case
sensitive this leaves the toplevel input/output signals unconnected. Fix
this by using lower case names everywhere.

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.

Clean ran for a project will clean only the project files.
Clean-all ran for a project will clean also the library files on which the project depends.
The clean commands will only remove specific files and directories.
The top Makefile allows several options(per suggestion from jameyhicks):
make fmcomms1.zed will run "make all" in projects/fmcomms1/zed/
make clean will run "make clean" for all the projects
make clean-all will run "make clean" for all the projects and libraries
make lib will run "make all" for the library files
Use a interface connection for the I2S stream instead of individually
connecting each of the signals. This make things a bit cleaner.
