Tested the patchset on top of Linus' tree.

Verified after enabling following debug message.
--- a/drivers/of/fdt.c
+++ b/drivers/of/fdt.c
@@ -865,7 +865,7 @@ int __init early_init_dt_scan_memory(unsigned long
node, const char *uname,

        endp = reg + (l / sizeof(__be32));

-       pr_debug("memory scan node %s, reg size %d, data: %x %x %x %x,\n",
+       pr_err("memory scan node %s, reg size %d, data: %x %x %x %x,\n",

Output before:
memory scan node memory, reg size 96, data: 20 10 30 10,

Output after:
memory scan node memory, reg size 64, data: 20 10 30 10,

Extra blank line here. Can be removed.
