Within the ColdFire hardware defines that is signified by MCFSDHC_BASE being defined with an address. The platform data for the ColdFire parts is including the SDHC hardware if CONFIG_MMC is enabled, instead of MCFSDHC_BASE. This means that if you are compiling for a ColdFire target that does not support SDHC but enable CONFIG_MMC you will fail to compile with errors like this: arch/m68k/coldfire/device.c:565:12: error: ‘MCFSDHC_BASE’ undeclared here (not in a function) .start = MCFSDHC_BASE, ^ arch/m68k/coldfire/device.c:566:25: error: ‘MCFSDHC_SIZE’ undeclared here (not in a function) .end = MCFSDHC_BASE + MCFSDHC_SIZE - 1, ^ arch/m68k/coldfire/device.c:569:12: error: ‘MCF_IRQ_SDHC’ undeclared here (not in a function) .start = MCF_IRQ_SDHC, ^ Make the SDHC platform support depend on MCFSDHC_BASE, that is only include it if the specific ColdFire SoC has that hardware module.
