Add support for cmod_a7 board.

[bl0x]

I just got a Cmod A7 35 today to play around with. So, here ya go!

@rroohhh , thanks for the review and comments!

crypto: I have no idea what this pin is for, and what is connected to it. But no problem, I could add it as a Connector.

sram: I forgot about it, mainly because I don't need it (now). I'll put it in.

Dear @rroohhh , am I still missing something?

[bl0x]

I think that all things are fixed now.

[bl0x]

I've rebased to current nmigen:master

@rroohhh Am I missing something to make this ready for merging?

[bl0x]

Hi,

I've migrated from nmigen->amaranth. The failing test is for genesys2, so unrelated to these commits.

Looks fine from what I can see, but @whitequark is the maintainer, I was just interested in the board and took a look :)

[bl0x]

I rebased onto main and updated. Also fixed two more things.

This PR now depends on PR 054b5c12b6488175bd16abcbc39e36312e647c95 (or a similar solution) to be merged. Otherwise the test for genesys2 will fail again.

Hi all,

I've also added support for the CMOD S7 board (very similar) and switched from using openocd to openFPGALoader. I'd be happy to get this merged.

Tests fail because of broken CI #200 .

[bl0x]

Updated this branch to remove nmigen compat layer and revert the change that introduced allowing strings as keys for describing pins. Now, the changes are just the two new board files.

[bl0x]

Sorry for nagging, but it would be very nice to get this merged. Is anything still missing?

[whitequark]

Thank you!

[bl0x]

great, thanks!
