From: "Mark A. Greer" <mgreer@animalcreek.com> Add the generic AM33XX AES module's device tree data and enable it for the am335x-evm, am335x-evmsk, and am335x-bone platforms. Also add Documentation file describing the data for the AES module. CC: Paul Walmsley <paul@pwsan.com> Signed-off-by: Mark A.
