The following patchset introduces Device Tree overlays, a method
of dynamically altering the kernel's live Device Tree.

This patchset is against mainline as of Friday Jan 4 2013.
(4956964 Merge tag 'driver-core-3.8-rc2' of \
 	git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core)

Note that a separate patch for the DTC compiler has been posted and
is required to compile the DTS files according to the documentation.
The patch is "dtc: Dynamic symbols & fixup support"

An implementation patchset for a beaglebone cape loader will follow,
but if you want to check out a working kernel for the beaglebone please
