[Buildroot] trying to use https://github.com/beagleboard/linux.git with buildroot

[Craig Swank]

I'll be interested in how your tests for the DTC patch go.  I'm not
having luck with the bone_capemgr at the moment and am considering
filing a bug at beagleboard/linux.

Will your tests involve compiling a .dtbo file and doing an echo command
to /sys/devices/platform/bone_capemgr/slots?  When I try to load my dtbo
file (for dallas one wire temperature sensor), the expected kernel
modules don't get loaded even though no errors show up in dmesg.
