For Seaboard's internal eMMC, this makes the difference between a 5.5MB/s and 10.2MB/s transfer rate. On Harmony, there wasn't any measurable difference on my cheap/slow ~2MB/s card.
Signed-off-by: Stephen Warren <swarren@nvidia.com> --- This depends on patch 1 in this series. I assume Grant or Arnd will apply them both to whatever branch usually takes .dts updates.
