Hey Christo,

Hi Oliver,

I start performance tests for eMMC, SD/MMC, USB, SATA SSD devices and will post the result when ready.

As a beginning I can say that eMMC is accessed via 4-bit bus without matter of the patch used.
There you are the content of /sys/kernel/debug/mmcX/ios (where X is number of eMMC or SD/MMC device).
