Remove litescope references from UART

[sbourdeauducq]

And do not call the WB bridge "frontend".

I've tried to change this, hope it's better.

[sbourdeauducq]

I don't think the name uart.wishbone is relevant. Those names should reflect the role that the UART has, either as a target device that receives the characters to write from a CPU through a bus (Wishbone, CSR, ...), or as an initiator device that masters a bus.

[sbourdeauducq]

Maybe uart.UART for the normal CSR target peripheral (since this is the most common, default, assumed role of a UART in a SoC), and uart.bridge.Wishbone for the initiator/bridge.

Thanks, so is it OK if I rename wishbone.py in bridge.py ? (I want to avoid creating a bridge directory for now since we only have a wishbone bridge, eventually later if we have others bridges (AXI, Avalon))

[sbourdeauducq]

Sounds good.

Done, thanks for the feedback!

Thanks for fixing it!
