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.
For example, I can access the memory of all in the U-Boot, but I may want to control the highmem on Linux,I do not want to show a specific area from kernel and userland.
Also, I object that your implementation is ARM specific. If such a feature gets added, it should be architecture independent.
I see. But arch_fixup_memory_node() is used by ARM only. So, we see to be dependent on the ARM is only this.
Thanks.
