Subject: [PATCH 0/5] DT Overlay based cape manager for TI's Beaglebone

Introducing a Device Tree overlay cape manager.

Using it it is possible to support the growing cape ecosystem for
the beaglebone, without having to hack a board file for each and
every cape plug combination.

It is possible to force load capes, and also possible to remove
them if need be (although precious few drivers support removal).

This patch is against the mainline kernel as of Jan 7 2013, top
of the tree: "5f243b9 Merge tag 'arm64-fixes' of \
	git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch640"

You will need to have the DTC compiler patch which was posted seperately
to the DTC mailing list "dtc: Dynamic symbols & fixup support", as well
as the I2C accessor patch "i2c-EEPROM: In kernel memory accessor interface" I
posted earlier.

Note that not many interesting capes are supported in the mainline kernel,
since the drivers some time to land in mainline, but you can see an
example of a (almost) feature complete linux kernel at:
