I meant other situations. The present issue with SD cards is, I believe, a symptom of a larger issue, which is that each architecture has its own idiosyncrasies with DMA. If there isn't an approach to deal with it in a systematic way then we'll keep finding more edge cases that need workarounds. I think that pushing this out to boards will be a mistake since this is an arch issue, not a board issue. This is different than, say, clocking, which is expected to vary by board depending on whether a clock is installed and its type and frequency. -- This is an automated message from the Apache Git Service.
