+Subject: [PATCH] arm64: dts: ipq8074: add reserved memory nodes
+
+IPQ8074 has multiple reserved memory ranges, if they are not defined
+then weird things tend to happen, board hangs and resets when PCI or
+WLAN is used etc.
+
+So, to avoid all of that add the reserved memory nodes from the downstream
+5.4 kernel from QCA.
+This is their default layout meant for devices with 1GB of RAM, but
+devices with lower ammounts can override the Q6 node.
