Good morning,

I tested it a few moments ago and to make it short: it doesn't work.

Here is the long story:

sdhci: Secure Digital Host Controller Interface driver
sdhci: Copyright(c) Pierre Ossman
sdhci-pltfm: SDHCI platform and OF driver helper
mmc0 bounce up to 128 segments into one, max segment size 65536 bytes
mmc0: SDHCI controller on 53fb4000.esdhc [53fb4000.esdhc] using DMA
sdhci-esdhc-imx 53fb8000.esdhc: Got CD GPIO
sdhci-esdhc-imx 53fb8000.esdhc: Got WP GPIO
mmc1 bounce up to 128 segments into one, max segment size 65536 bytes
mmc1: SDHCI controller on 53fb8000.esdhc [53fb8000.esdhc] using DMA
oprofile: no performance counters
oprofile: using timer interrupt.
mmc0: new high speed MMC card at address 0001
