kexec-tools:kexec/arch/arm/kexec-arm.c:get_memory_ranges() is telling you that
However, you /proc/iomem is telling you:
42000000-5fffffff : System RAM
get_memory_ranges() is reading /proc/iomem and finding out the available ram
locations. So, can you debug this kexec-tools function and see why you do not
get the range which is coming from /proc/iomem
