[PATCH 1/2] of: of_reserved_mem: only call memblock_free for normal reserved memory

[PATCH 1/2] of: of_reserved_mem: only call memblock_free for normal reserved memory

[Dong Aisheng]

For nomap case, the memory block will be removed by memblock_remove()
in early_init_dt_alloc_reserved_memory_arch(). So it's meaningless to
call memblock_free() on error path.

[PATCH 2/2] of: of_reserved_mem: mark nomap memory instead of removing

[Dong Aisheng]

Since commit 86588296acbf ("fdt: Properly handle "no-map" field in the memory region"),
nomap memory is changed to call memblock_mark_nomap() instead of
memblock_remove(). But it only changed the reserved memory with fixed
addr and size case in early_init_dt_reserve_memory_arch(), not
including the dynamical allocation by size case in
early_init_dt_alloc_reserved_memory_arch().

Good practice is to Cc the people involved in referenced commits.
Adding them now. This code is a minefield so I'd like other eyes on
it.
