dvisampler/edid: fix sda sampling, needs to be similar to scl.
...
Video sources with high scl frequency were not able to access EDID information through I2C.
I2C start was not detected correctly and was randomly reseting the fsm during transfers.(seen with litescope)

sdram/phy/s6ddrphy: add S6QuarterRateDDRPHY to run DDR3 at higher frequencies.
...
Built on top of S6HalfRateDDRPHY, exposes a 4 phases DFI interface to the controller with a 2x slower clock.
Validated on the Numato Lab opsis board (50MHz sys_clk/ DDR400), should also work on the Novena laptop (same DDR3 module).

both into static images such as the BIOS as well as
into shared libraries.

misoclib/com/uart: remove irq condition parameters and use "non-full" for tx irq, "non-empty" for rx irq.
...
An optimal solution for both sync and async mode is not easy to implement, it would requires moving CDC out of UART module and handling in the PHY with AsyncFIFO or minimal depth.
For now use the solution that works for both cases. We'll try to optimize that if we have performance issues.
