Help text

Say Y for an MMC/SD socket connected to general I/O pins (but not a complete synchronous serial ports), or for devices using the SPI protocol on general I/O pins. Slow and slows down the system. Say m to build it as a module, which will be called spi_crisv32_gpio. (You need to select MMC separately.)
