- 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.
- Signed-off-by: Robert Marko <[email protected]>
