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.
|
