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.

If all channels are selected for read the values and ready signals from every
transceiver are combined. Each element merges his signals with the previous.
The first element of the chain must assume the previous channel is always ready.
This reverts commit 829e4155ca.
The first element of the read chain must assume there is no valid element
in front of it. For each element the ready signal of the transceiver should be
routed if the channel is selected either by channel number or broadcast.
When the current element is not selected it should forward the ready signal from
the previous element, however this is not the case for the first one.
Having a constant 1'b1 connected to the ready input of the first element
corrupts the first read of the first channel after a channel switch.
This change will break broadcast reads.
For fixing "Failed to reset the device and set SPI Config"
error, both clockPolarity and clockPhase should be disabled
or both enabled. By default both are unset.

Adds a magic identification value of 0x54444443 at word address 0x3.
It is derived from the ASCII String "TDDC" interpreted as a big-endian
32-bit unsigned integer.

For GTH3/4 64b66b mode add a second clock that drives CLKUSR with a clock
that is 2x of the CLKUSR2 (lane rate/66),
CLKUSR = 2 x CLKUSR2
CLKUSR = lane rate / 33
This can be driven from the GT reference clock or second out clock div2.
This commit also:
- fix eyescan scale on GTY
- remove irrelevant parameters
If R1 mode is first syncronized to the dac clock domain will prevent its
usage if the dac clock is missing. In such case the synchronization will not
propagate.
Depending on FPGA technology the physical layer uses different
deserialization factors and corresponding clock division factors to
divide the source synchronous interface clock. This must be
exposed to software so it can act on it while setting the DDS rate.
Xilinx CMOS clock ratio - 4
Xilinx LVDS clock ratio - 4
Intel CMOS clock ratio - 1
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 module creates sync header alignment described in section 7.6.1 of
the JESD 204C specification.
The alignment relies on the bitslip capability of the connected
transceiver.
