Titanium Ti375 C529 support

[Dolu1990]

Hi,

This is just to notify that i'm working on adding support for this dev kit : https://www.efinixinc.com/products-devkits-titaniumti375c529.html

Let's me know if you have done any related work previously ^^

[Dolu1990]

Got the uart / sdcard / usb host / debian to work.

Nice, thanks for sharing @Dolu1990! Not sure anyone started adding LiteX-Boards support to it.

WIP : https://github.com/Dolu1990/litex-boards/tree/ti375_c529

Also got HDMI to work (https://www.digikey.fr/fr/products/detail/efinix-inc/EFX-HDMI/17084519)

Done with https://github.com/litex-hub/litex-boards/pull/610, thanks @Dolu1990!

@Dolu1990: You different PR have been merged, would you mind doing a test with upstream repos? (I also ordered a Ti375 to also be able to do some tests but the board is not yet there).

@enjoy-digital Just tried with litex + litex-boards repository. Seems all good, constraints look good and it does run debian at 200 Mhz ^^

Thanks !

Great, thanks for the feedback! We can probably close this issue since completed.
