not in fact it seems to have been broken from a long time and I think
I'm responsible of that in 37865fe91582582a6f6c00652f6a2b1ff71f8a78
"mmc: sdhci-esdhc-imx: fix timeout on i.MX's sdhc"
because unlike the i.MX35 it seems that the i.MX25 manages to read
properly the partition table even without the timeout quirk and it
seems that I didn't do more extensive tests for this patch.
