2018-03-09sdcard: Add the Tuning Command (CMD19)Philippe Mathieu-Daudé
From the "Physical Layer Simplified Specification Version 3.01": A known data block ("Tuning block") can be used to tune sampling point for tuning required hosts. [...] This procedure gives the system optimal timing for each specific host and card combination and compensates for static delays in the timing budget including process, voltage and different PCB loads and skews. [...] Data block, carried by DAT[3:0], contains a pattern for tuning sampling position to receive data on the CMD and DAT[3:0] line.
