Just having a quick look at the code and a few printouts from sdhci.c
indicates that SDIO IRQs are enabled but in the end the eSDHC controller
doesn't report any IRQs. On the other hand, the IRQ handling for SDIO
IRQs in sdhci.c doesn't follow the steps described in the i.MX35
Reference Manual (but that doesn't explain why there is not one single
SDIO IRQ reported).
