These symbols are part of the drivers/mmc/host/sdhci.c which is build
when CONFIG_MMC_SDHCI is enabled. However CONFIG_MMC_XENON_SDHCI depends
on CONFIG_MMC_SDHCI_PLTFM which depends on CONFIG_MMC_SDHCI.

So I wonder how we can have a sition with sdhci-xenon.c built but not
sdhci.c.

Any idea?

Thanks,

Gregory
