[PATCH 4.19 121/139] ARM: dts: rockchip: Remove @0 from the veyron memory node

From: Greg Kroah-Hartman
Date: Tue Dec 04 2018 - 06:26:12 EST


4.19-stable review patch. If anyone has any objections, please let me know.

------------------

From: Heiko Stuebner <heiko@xxxxxxxxx>

commit 672e60b72bbe7aace88721db55b380b6a51fb8f9 upstream.

The Coreboot version on veyron ChromeOS devices seems to ignore
memory@0 nodes when updating the available memory and instead
inserts another memory node without the address.

This leads to 4GB systems only ever be using 2GB as the memory@0
node takes precedence. So remove the @0 for veyron devices.

Fixes: 0b639b815f15 ("ARM: dts: rockchip: Add missing unit name to memory nodes in rk3288 boards")
