From f853f00531646535c686b493d7826e69dd1a1b46 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 5 Jun 2019 11:34:32 -0500 Subject: [PATCH] arm64: dts: ti: k3-am65-mcu: Add the MCU RAM node Add the on-chip SRAM present within the MCU domain as a mmio-sram node. The K3 AM65x SoCs have 512 KB of such memory. Any specific memory range within this RAM needed by a software module ought to be reserved using an appropriate child node.
