old implementation felt too "cutsy"
this makes for a cleaner usage model (simple shift with param)
also splitting out enable but, not making the CTIMER mistake again
-adding reset signals to synchronizer to solve startup issues
-setting config in test bench for speedup, default reg config now correct
-fix (my) stupid bug in etx_arbiter
-adding reset to fifo (todo: review this!)
-reviewing "all red" from waveforms is a must. Red (x) on data is ok, but leaving them on control signals is asking for trouble. Better safe than sorry when it comes to reset.
-pll bypass for clocks (customer request)
-adding dividers on all clocks (tx/cclk)
-adding reset block (clearer)
-using commong clock_divider block
-need to clean up divider block later today, slightly broken:-)
-added register read/write properly
-removed redundant wrapper layers in maxi/saxi
-changed over to "emesh" interface from packet 103 bit data
-cleaned up maxi
-cleaned up saxi
-removed redundant signals in elink interface (user,lock,..)
-added wrapper to fifo (to carry emesh interface through)
Now comes the fun part of testing
-adding clock bypass mode for esystx[12]
-removing monitor feature on erx
-remove loopback support from doc
-add clock bypass mode for esysclk
-shortening register names (descriptive enough)
-added debug signal information
-moving registers to elink
-making elink version programmable (to support plug in boards)
-reorganized debug signals and added stickys
-added timeout for axi slave
-removed embox status bit (redudant, don't poll status)
-renamed EMBOX0-->EMBOXLO
-moved datain interface straight to ecfg (cleanup)
-changed etx arbiter priority to increase stability
-created the esaxi_mux block
-fixed some missing ports issues in stubs
Now comes the fun part...verification...
Andreas
-back and forth with emmu, memory is now inside (for good)
-renamed clocks in etx to clarify
-updated logic in protocol and disty
-updated clock module
...one more review pass and we are ready for testing...
-this may break already broken projects
-creates a Verilog top level (instead of using Vivado block level design)
-integrates mmy and mailbox (not completely integrated)
-compiles...
-pours in all of the code from the archive
(some new logic created)
