   5 Subject: [PATCH net-next] arm64: dts: mt7986: move ilm in a dedicated node
   6
   7 Since the ilm memory region is not part of the RAM SoC, move ilm in a
   8 deidicated syscon node.
   9 This patch helps to keep backward-compatibility with older version of
  10 uboot codebase where we have a limit of 8 reserved-memory dts child
  11 nodes.
