This patch series includes several improvements and boosted the read performance from 13 MB/s to 32 MB/s (at 60MHz clock rate) on a Odroid C2 with a 128GB eMMC module. Higher frequencies needed tuning in my case. With some hacked test tuning I reached 52 MB/s at 200MHz. With a 8GB card 200MHz were stable out of the box, but with less performacne.
