So, this is for a not yet (but I believe the intention is to post soon)
mainline board.  My concern here is that a given bad SD card would /
should show the problem on any board, so we should be adjusting our
caps globally, yes?  Or is there a board (and not SoC) specific part
of the equation?  Thanks!
