misc: Beaglebone capemanager

A cape loader based on DT overlays and DT objects. This is the beaglebone cape manager which allows capes to be automatically probed and instantiated via means of a device tree overlay deduced from the part-number and version contained on the cape's EEPROM. The reference manual contains information about the specification and the contents of the EEPROM. http://beagleboard.org/static/beaglebone/latest/Docs/Hardware/BONE_SRM.pdf Documentation about the workings of the cape manager is located in Documentation/misc-devices/bone_capemgr.txt This driver is using the nvmem framework interface to retrieve the data stored on the baseboard and cape EEPROMs. Signed-off-by: Pantelis Antoniou <[email protected]>
