Tanix TX6 box has a 32 GB eMMC module. With changes in this series, I get following figures with hdparm -tT: /dev/mmcblk2: Timing cached reads: 1638 MB in 2.00 seconds = 818.44 MB/sec Timing buffered disk reads: 376 MB in 3.01 seconds = 124.74 MB/sec First patch fixes regulator node names. Second patch sets proper power supplies to GPIO banks and third adds eMMC support. Please take a look.
