Laszlo Nagy b90c2e79dc jesd204_rx: add parameter for input pipeline stages
Pipeline stages must be implemented on register so placer can spread it
cross the device. Use the shreg_extract attribute to avoid SRL
inference.

Lars-Peter Clausen d72fac4b1e Add missing timescale annotations
For consistent simulation behavior it is recommended to annotate all source
files with a timescale. Add it to those where it is currently missing.

jesd204: Add RX error statistics (#98)
* 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

Istvan Csomortani 0e099b6f08 jesd204_rx: Add dynamic multi-link support
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.

Istvan Csomortani 09ff1f3a77 jesd204: Fix file names
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.
