Dual clock mode is introduced in link layer to support different
datapath widths on the transport layer than on physical layer.
- Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b
- Device clock : Link clock * input data path width / output datapath width
Supports four clock configurations, single or dual clock mode with or
without external device clock.
The configuration interface reflects the dual clock domain.
Add support to JESD204 RX and TX core for 8-byte 8b/10b link mode,
and frame alignment character replace/insert with or without scrambling.
Add support for xcelium simulator to jesd204/tb
Increased cores minor version.
Add support for RX frame alignment character checking when scrambling is enabled and
for link reset on misalignment.
Add support for xcelium simulator to jesd204/tb
* jesd204: Add RX error statistics
Added 32 bit error counter per lane, register 0x308 + lane*0x20
On the control part added register 0x244 for performing counter reset and counter mask
Bit 0 resets the counter when set to 1
Bit 8 masks the disparity errors, when set to 1
Bit 9 masks the not in table errors when set to 1
Bit 10 masks the unexpected k errors, when set to 1
Unexpected K errors are counted when a character other than k28 is detected. The counter doesn't add errors when in CGS phase
Incremented version number
A multi-link is a link where multiple converter devices are connected to a
single logic device (FPGA). All links involved in a multi-link are synchronous
and established at the same time. For a RX link this means that the SYNC signal
needs to be propagated from the FPGA to each converter.
Dynamic multi-link support must allow to select to which converter devices on
the multi-link the SYNC signal is propagated too. This is useful when depending
on the usecase profile some converter devices are supposed to be disabled.
Add the cfg_links_disable[0x081] register for multi-link control and
propagate its value to the RX FSM.
All the file names must have the same name as its module. Change all the
files, which did not respect this rule.
Update all the make files and Tcl scripts.
The DEGLITCH state of the RX state machine is a workaround for misbehaving
PHYs. It is an internal state and an implementation detail and it does not
really make sense to report through the status interface.
Rework things so that DEGLITCH state is reported as part of the CGS state
on the external status interface.

Add Qsys IP scripts as well as SDC constraint files for the ADI JESD204
peripherals. This allows them to be instantiated and used on Altera/Intel
platforms.
