-Subject: [PATCH] of: of_reserved_mem: Ensure cma reserved region not cross the
- low/high memory
-
-Need ensure the cma reserved region not cross the low/high memory boundary
-when using the dynamic allocation methond through device-tree, otherwise,
-kernel will fail to boot up when cma reserved region cross how/high mem.
