For analyzing memory blocks we can either use the memblock=debug command line argument which creates massive output or a debug file system.
Select CONFIG_ARCH_KEEP_MEMBLOCK to provide a debugfs at /sys/kernel/debug/memblock to analyze memory blocks. The same is already done for arm, arm64, mips, powerpc.
The actual provisioning of the file system depends on CONFIG_DEBUG_FS.
