- allow specifying the name of Axi Lite interface from the peripheral were to connect the control bus
- some DDR controllers have an Axi Lite control interface, this creates
a second address segment which causes issues, differentiate the memory
segment from control registers segment
Vivado cannot nest multiple block designs than two layers. This makes
replication of designs difficult.
Create a hierarchy around the Versal transceiver that includes also the
converters, this type of interface would match the util_adxcvr
interface.

For ad9081/a10soc project, the RX_LANE_RATE and TX_LANE_RATE were computed
from SAMPLE_RATE. Remove SAMPLE_RATE and add RX_LANE_RATE and TX_LANE_RATE
as parameters. Update also computation examples from comments.

Parametrizable project for the QUAD-MxFE platform ADQUADMXFE1EBZ,
ADQUADMXFE2EBZ, ADQUADMXFE3EBZ
Default mode set to:
TX JESD204C MODE 11, M=16, L=4
RX JESD204C MODE 4, M=8, L=2
For 204C 64B66B mode as physical layer the Xilinx Phy is uesd.
This adds a Readme.md to each project directory with pointers to project
documentation in the wiki, and the drivers (if they exist). This will
help with some autogenerated doc in the wiki, that is generated with the
innovatily named "wiki_summary.sh" shell script that parses through
these Readme.md files, and generates a summary table.

Occasionally with zed, the implementation failed at the placement stage where
the tool could not fit the logic cells inside a single clock region,
constraint required by the usage of regional clock buffers.
This commit allows the usage of the global clock buffers which help the tool
in such cases and allow a larger application logic to be implemented in fabric.
Fix CONVERTER_RESOLUTION parameter setting for ad9250. Also deleted the
setting of BITS_PER_SAMPLE and DMA_BITS_PER_SAMPLE for ad9250 since they
are set by default to the desired values.

For CMOS case, lane rates are so low that reference clock of the source
synchronous interface can be routed on non-clock routes. The delays on
the clock line are adjusted by the digital interface tuning controlled
through software.
Lock down clock buffers on Rx and Tx interfaces, this avoids suboptimal
placement which causes large skew between clocks at the serdes pins.
1. Reduce max allowed skew between source synchronous clocks that can
occur due PCB differences. 250ps represents a difference more than an
inch.
2. In order to reduce skew between source synchronous clock and the
divided clock instruct the tool to use a common clock root for them.
The default address space for a new bridge is 256 Kbytes. Add an
avl_address_width attribute to the ad_cpu_interoconnect porecess to
define other address space sizes if needed.
The avl_peripheral_mm_bridge will have an 128 Kbyte address space from
address 0x0000.
Modified the project such that there is only one data path for the ADC data: deleted one of the JESD tpl instances, one of the cpack instances and one of the dma instances.

This commit adds a new synthesis option to the design, that controls
whether an internal clock domain crossing will be generated. Disabling
this option allows you to use a synchronization signal that is
synchronized to the write clock domain externally, and possibly shared
between multiple devices.
The default value retains the old behavior.

The derived clocks of the zynqmp core are not calculated correctly due
rounding issues, instead of 100MHz the value of 99999001 is received
causing warnings during system validation.
This can be fixed/worked around with the proper reference clock
definition.
The 2020.1 Xilinx tools have a different tcl procedures to build the boot.bin
file.
This commit updates the adi_make tcl flow for the new tools. The new
process is not backwards compatible with tools older than 2020 version.
In order to workaround optimization issues hit in Vivado 2020.2,
set ADI_USE_OOC_SYTHESIS variable by default to 1. This will build
projects in Out Of Context mode.
Projects can be build in Project Mode by exporting ADI_USE_OOC_SYTHESIS=n.
Update vivado version to 2020.2:
- update default vivado version from 2020.1 to 2020.2
- add conditions to apply specific contraints only in Out Of Context mode.
- update DDR controler parameters for vcu118 and kcu105 dev boards

The goal of this commit is to make sure there isn't any significance to
the order in which parameters of ad_connect are specified.
As an example, previously you could only `ad_connect target VCC`, while
`ad_connect VCC target` would fail.
Note: This code intentionally ignores bd_{,intf_}ports, because
these can all be treated as bd_pins.

This commit fixes the 16.5Gbps lane rate case where the link drops
after few seconds an initial successful link up happens.
A few seconds delayed calibration process can workaround this but with
having the differential drivers swing increased this is no longer
required.
This will allow building base test harnesses and place on top of them
existing block designs for simulation purposes.
Test harnesses will contain basic functionality like
- clock and reset generators
- AXI master to aid register access of the cores.
- memory model of the DDR
- interrupt controller
Existing procedures (ad_mem_hp0_interconnect, ad_cpu_interconnect, ... ) will
connect to this harness as they do to a real base design.
To support deterministic latency with non-power of two octets per frame
(F=3,6) the interface width towards the transport layer must be resized
to match integer multiple of frames.
e.g Input datapath width = 4; Output datpath width = 6;
for F=3 one beat contains 2 frames
for F=6 one beat contains 1 frame
The width change is realized with a gearbox.
Due the interface width change the single clock domain core is split
in two clock domains.
- Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b
- lane rate / 20 for input datapath width of 8 octets 8b10b
- lane rate / 66 for input datapath width of 8 octets 64b66b
- Device clock : Link clock * input data path width / output datapath width
Interface to transport layer and SYSREF handling is moved to device clock domain.
The configuration interface reflects the dual clock domain.
If Input and Output datapath width matches, the gearbox is no longer
required, a single clock can be connected to both clocks.
In most of the standalone projects the generic project creation flow is not followed. The project's device
is defined manualy. This fix makes sure that those projects still builds without an issue.
NOTE: In these case we should use adi_project_create directly in system_project.tcl.
Without defining this signal, the UART lines receive garbage data
when no cable is connected to the J4 USB UART port.
The GPIO9 is enabled in the reference base design along with the
4MA CURRENT_STRENGTH constraint on the UART pins
When phase alignment is active, the PFD frequency value should be used
as outclk1 actual frequency.
The configuration interface of the fPLL does not support fractional values.
If the reference clock is fractional, the tool will throw an error that requirement
above is not respected.
Round up the reference clock for the SERDES and the lane rate in order to
overcome this issue, until it's not fixed by Intel.

-change the video memory interfacing from f2h_axi_slave to
f2h_sdram0
- add f2h_sdram1 port as the default interface for converter DMA
- set as default the full HD resolution at 60 FPS (pixel clock 148.5MHz)
- use a second 200MHz(198MHz) clock from the pixel_clk_pll, as DMA source
to destination clock.
