REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1140 Some of the boards report that just after we change the clock frequency to 200MHz link is unable to stabilize fast enough and when driver sends the CMD13 it will often fail randomly with CRC error. To protect against this kind of random failures this patch series will make the driver retry the commands that failed due to random CRC errors. Since async code has not yet been tested it has been put into separate patch. That patch is not needed to solve most pressing CMD13 issues.

Please grant me some time to review and validate the series. I will try to give my feedbacks no later than early next week.
