   4 Subject: [PATCH] arm64: dts: ipq8074: add reserved memory nodes
   5
   6 IPQ8074 has multiple reserved memory ranges, if they are not defined
   7 then weird things tend to happen, board hangs and resets when PCI or
   8 WLAN is used etc.
   9
  10 So, to avoid all of that add the reserved memory nodes from the downstream
  11 5.4 kernel from QCA.
  12 This is their default layout meant for devices with 1GB of RAM, but
  13 devices with lower ammounts can override the Q6 node.
