Subject: [PATCH] of: of_reserved_mem: clean-up reserved memory with no-map
Date: Sun, 28 Apr 2024 21:55:05 +0900	[thread overview]
Message-ID: <20240428125505.434962-1-skseofh@gmail.com> (raw)

From: Daero Lee <daero_le.lee@samsung.com>

In early_init_dt_reserve_memory we only add memory w/o no-map flag to
memblock.reserved. But we need to add memory w/ no-map flag to
memblock.reserved, because NOMAP and memblock.reserved are semantically
different.
