The trueDualPortRAM component (https://hackage.haskell.org/package/clash-prelude-1.6.3/docs/Clash-Explicit-BlockRam.html#v:trueDualPortBlockRam) has no API to set the initial contents like blockRam (https://hackage.haskell.org/package/clash-prelude-1.6.3/docs/Clash-Explicit-BlockRam.html#v:blockRam).

As far as I know there is no technical reason to not be able to define the initial contents and the added value of this functionality seems very significant to me.

Note that our asynchronous RAMs also only have undefined initial contents. It could be worthwhile to add it there as well.
