I made a test with these quirks enabled. But the result was the same.
Loading the module also ends in the known error "mmc0: Timeout waiting
for hardware interrupt".
I am a little bit confuced. Seems your freescale kernel uses another
mmc driver for your imx51? My kernel config, the one for imx35
processors, includes "/drivers/mmc/host/sdhci-esdhc-imx.c" =>
CONFIG_MMC_SDHCI_ESDHC_IMX and not "drivers/mmc/host/sdhci-of-esdhc.c"
=> CONFIG_MMC_SDHCI_OF_ESDHC. CONFIG_MMC_SDHCI_OF_ESDHC cant`t be
enabled because CONFIG_PPC_OF is not defined. And I think
CONFIG_PPC_OF is power pc stuff.
