A quick shout out to see if anybody has any experience with setting up 
SPI on a BeagleBoard xM Rev C. I have applied patches as stated in the 
eLinux wiki to no avail. Patches are listed below:

I am running kernel 2.6.37 and u-boot 2011.06 and have applied the
following patches:

u-boot for pin muxing:

kernel for spidev config and loading of the driver:

SPI shows up in /sys but there is no node created in /dev.

If anyone can see any faults or have any suggestions I would love to 
hear them as i'm coming close to bald!

I also have a post listed on the BeagleBoard Google Board:

Kind Regards,
