Open source hardware is such a fascinating concept, I had thought of such examples but I always assumed they would be the case of risc-v chips, I wonder how it's an arm chip

I always thought that one day we will get completely open source risc-v chips that if another company wants, they can create in their own chip-making process (I imagine it to be beyond extremely difficult but still it opens up a pathway)

what's the progress of risc-v nowadays?

Also Can you please link me other such projects like this, it would be good to have a bookmark/list of all such projects too
