Hi, This series adds ocmcram nodes to use the mmio-sram driver to dra7.dtsi for use by all dra7xx and am57xx platforms. Not all ocmcram regions are present on every SoC variant so all possible nodes are added to the parent dtsi with the optional nodes marked "disabled". Board dts files that are known to have silicon supporting them can then enable them as needed. Patch two adds a "dummy" reserved region in the ocmcram1 node that acts as a placeholder for the region that is needed by secure software running on secure variants of the SoC. It is left as size zero with the intention that either: - The bootloader will step in and adjust the size based on what the secure software that is in use requires. - A board dts with specific requirements will override the node with appropriate size. The SRAM bindings in use are described in this patch [1] that is part of a series that adds SRAM regions for OMAP3 platforms.
