Does MontaVista 5.0 support SPI on DM6446?

Hi All,
We are doing a project of which Davinci DM6446 is used. We found that SPI device is not supported in DM6446 kernal(MontaVista 5.0 Linux-2.6.18).
In Kconfig file, it reads: SPI is only officially supported for DM646x and DM355.
 So can anyone tell us how to modify the core or which pitch could be used to drive the SPI on DM6446? Many thanks!
regards,
swinter.

    Hi Swinter,

    Ideally DM6446 should also be using the same SPI driver present in drivers/spi folder (davinci_spi_master.c). You may have to add DM6446 platform specific data in the kernel. For this you can refer to arch/arm/mach-davinci/davinci_spi_platform.c file.
