Usually, when CONFIG_OF_LIBFDT is enabled, U-Boot is set to the FDT memory information that is set in the U-Boot. This patch disables this behavior.

Please explain why you would want to do this. To me it makes no sense. Either U-Boot knows the correct memory size, then it should pass it to Linux. Or it does not, then U-Boot should be fixed.
Also, I object that your implementation is ARM specific. If such a feature gets added, it should be architecture independent.
This has shown up before in the context of platforms with >4GB memory and we "correct" the node by reducing the system memory, which is incorrect. I agree this needs to be done for more than just ARM however.
It is one of the reasons of this patch that you wrote.
Thanks, Nobuhiro
