On ES2.0? I wonder how if not even the pinmux is there ;)

Changing the config a little I have

--cut --
CONFIG_MMC=y
# CONFIG_MMC_DEBUG is not set
# CONFIG_PWRSEQ_EMMC is not set
# CONFIG_PWRSEQ_SIMPLE is not set
CONFIG_MMC_BLOCK=y
CONFIG_MMC_BLOCK_MINORS=8
# CONFIG_SDIO_UART is not set
# CONFIG_MMC_TEST is not set

#
# MMC/SD/SDIO Host Controller Drivers
#
# CONFIG_MMC_ARMMMCI is not set
# CONFIG_MMC_SDHCI is not set
# CONFIG_MMC_TIFM_SD is not set
# CONFIG_MMC_SPI is not set
CONFIG_MMC_TMIO_CORE=y
CONFIG_MMC_SDHI=y
CONFIG_MMC_SDHI_SYS_DMAC=y
CONFIG_MMC_SDHI_INTERNAL_DMAC=y
-- cut --

now.

As SDHCI is disabled, now, I don't get anything SD/MMC related in the 
boot log any more. Not even an error message. Hmm ...

The device tree has [1].

Best regards
