On J721e and J7200, MCU R5 core (boot master) itself would run Device Manager (DM) Firmware and interact with TI Foundational Security (TIFS) firmware to enable DMA and such other Resource Management (RM) services. So, during R5 SPL stage there is no such RM service available and ti_sci driver will have to directly interact with TIFS using DM to DMSC channels to request RM resources. Therefore add DT binding and driver for the same. This driver will handle Resource Management services at R5 SPL stage.

Device Tree Bindings Staging Area ================================= This directory contains device tree bindings for U-Boot. These follow along with Linux kernel bindings, with a few additions. By adding the files here, U-Boot patches can clearly show thees additions. This makes it easier for device tree people to review these additions in patches sent to the U-Boot mailing list. The intent IS to commit these files to U-Boot. Hopefully at some point the files will be stored in another repo (shared with Linux) which is brought in as needed. Changes here are intended to mirror changes in the Linux Documentation/devicetree/bindings/ directory. sjg@chromium.org 17-Jan-12
