From 1e48754f2c6ed745299ed179ae90f695abe7ca87 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Thu, 9 Jul 2020 18:19:51 -0500 Subject: [PATCH] ARM: dts: omap5-uevm: Add CMA pools and enable IPU & DSP The CMA reserved memory nodes have been added for the IPU and DSP remoteproc devices on the OMAP5 uEVM board. These nodes are assigned to the respective rproc device nodes, and both the IPU and DSP remote processors are enabled for this board. The current CMA pools and sizes are defined statically for each device. The starting addresses are fixed to meet current dependencies on the remote processor firmwares, and will go away when the remote-side code has been improved to gather this information runtime during its initialization. An associated pair of the rproc node and its CMA node can be disabled later on if there is no use-case defined to use that remote processor.
