Subject: [PATCH net-next 1/3] net: ethernet: mtk_wed: move ilm a dedicated dts
|
|
node
|
|
|
|
Since the ilm memory region is not part of the RAM SoC, move ilm in a
|
|
deidicated syscon node.
|
|
This patch helps to keep backward-compatibility with older version of
|
|
uboot codebase where we have a limit of 8 reserved-memory dts child
|
|
nodes.
|
|
Keep backward-compatibility with older dts version where ilm was defined
|
|
as reserved-memory child node.
|
|
