With this dts node for mmc2, the eMMC runs at the following ios settings: clock: 52000000 Hz vdd: 21 (3.3 ~ 3.4 V) bus mode: 2 (push-pull) chip select: 0 (don't care) power mode: 2 (on) bus width: 3 (8 bits) timing spec: 8 (mmc DDR52) signal voltage: 0 (3.30 V) driver type: 0 (driver type B) Note the mmcblk1boot0/boot1 partitions are unused as the BROM will load the SPL from 8k from the start of the main blockdev, just as with a regular sdcard in mmc0.
