From 78eccc2ac98e4166def294f02283f21cefd89591 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 5 Jun 2019 11:34:33 -0500 Subject: [PATCH] arm64: dts: ti: k3-j721e: Add the MCU SRAM node Add the on-chip SRAM present within the MCU domain as a mmio-sram node. The K3 J721E SoCs have 1 MB of such memory. Any specific memory range within this RAM needed by a driver/software module ought to be reserved using an appropriate child node.
