A user will usually not know if he is using the v2 or v3 controller without reading the help text. If you change it to config MMC_SDHCI_PXAV2 tristate "Marvell PXA168 SD Host Controller support (PXAV2)" default CPU_PXA168 config MMC_SDHCI_PXAV3 tristate "Marvell MMP2/PX9XX SD Host Controller support (PXAV3)" default CPU_MMP2 || CPU_PXA910 you increase the chances of users getting the configuration right.
