Is it not sufficient to pass some "mem=" boot argument? We even have automatic support for this in U-Boot (see the CONFIG_PRAM feature). > > Also, I object that your implementation is ARM specific.

All architectures that support the device tree update the memory size for Linux, so we should find a generic way to handle this. Actually we should always strive to reduce this arhitecture specific code.
