Subject: [PATCH] arm64: dts: Add/fix /memory node unit-addresses
'/memory' nodes always have a 'reg' property, and therefore should have
a unit-address with just plain hex (i.e. no commas). Fix all the arm64
'/memory' nodes.
It's possible that some bootloader depends on /memory (arm32 ATAG to DT
code does for example). If so, the memory node should be commented with
that requirement.
Signed-off-by: Rob Herring (Arm) <robh@...nel.org>

SoC maintainers, please take this directly.
arm32 is much worse, but the platforms using ATAG to DT code can't be
changed and I don't know which ones those are.
