MPC8313 & SPI

[MarkB]

I am trying to understand how the SPI interface works in this BSP.  I don't see any of the spi devices in /dev/.  Do they need to be created by hand using 'mknod'?  Are they located elsewhere?

Also, does anyone have some example SPI code that talks to the MPC83* SPI driver?

I've replaced my Rev A4 boards with the new Rev C hardware and I still can't get spidev up and running.

I've recompiled the kernel with SPI support and I am loading devfs.  However, I see that udevd is present on the RDB but it isn't running at startup.

Do I need both devfsd and udevd?  It seems like I wouldn't.

I've even tried passing mount=devfsd as a boot parameter.

FYI, I am using the spidev_test.c compiled binary as a starter.  I always get "can't open device: No such file or directory" which suggests to me that udev or devfs is borked.

I've also tried the BSP kernel and 2.6.28.6.
