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:
