Hi, I'm currently working on adding FuseSoC support for LowRISC. So far I have managed to build a bitstream, but not test it. Need a bit of clean up, add simulation support and more, but generally it looks good. As a part of this process, I'm looking for fixes in code that has been brought in from other projects and should be sent upstream. I have so far gone through the changes for the ps2 code, sent one trivial fix upstream and kept some other patches as LowRISC-specific for now. When it comes the the SD card controller however, there are significant changes, and I can't find much in the history. Already when it was checked into the minion_subystem repo it seems to have been heavily modified from the upstream version. Could anyone shed some light on this. I would really like to see relevant patches being fed back upstream. Happy to do the actual work, but I need some context for what the changes are supposed to do Also, as a code-deduplication fascist, are there any other pieces of code that has been inherited and copied into LowRISC that I can look at? //Olof
