Hi everybody, I'm looking for an MMC/SD driver using the MPC8248 SPI interface. Does anyone know if such a driver exist, or if some code has already been written ?
If no such project exists, could anyone outline the basic architecture of such a driver ? As recent Linux kernels include an SPI class, I suppose I should write a generic MMC/SD-SPI driver which would work with any SPI controller, and write an SPI driver for the MPC8248 (which seem to have a similar interface to the already supported MPC83xx). How should the generic MMC/SD-SPI driver be mapped to specific SPI ports ? Best regards, Laurent Pinchart
