Neorv32 complex setups

[zipotron]

Hello. I have created a repo for implement the SDRAM driver for ULX3S and other complex setups here:
https://github.com/zipotron/neorv32-complex-setups
Please, feel free to give opinions about how is being done.
Thanks!

Looks good so far!
So this is a setup with SDRAM, right? Some more details in the README would be nice, maybe including a memory map.
If you like you can add that repository to the list of "external" setups in setups.

Hi! I just added in the list of "external" setups, is part of the PR #213!

[zipotron]

Thanks! You are right! I will, just need time, also, before, I need to finish the TOP, I could set the PLL, but the wishbone bus is not wired yet...

@zipotron instead of copying a BoardTop into the submodule, it should be possible to override BOARD_SRC (

neorv32/setups/osflow/Makefile

Line 19 in 6294540

BOARD_SRC=./board_tops/neorv32_$(BOARD)_BoardTop_$(DESIGN).vhd \

). Maybe it needs an adjustment similar to #214.

This is a good idea... I will investigate! Thanks

[zipotron]

I tried, but I think my Makefile knowledge in not enough deep for do it

I will give a second try in the incoming weeks...
