Subject: [OpenRISC] [PATCH 05/15] h8300, nds32, openrisc: simplify detection of memory extents
Date: Tue, 28 Jul 2020 05:13:05 -0000 [thread overview]
Message-ID: <20200728051153.1590-6-rppt@kernel.org> (raw)
In-Reply-To: <20200728051153.1590-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
Instead of traversing memblock.memory regions to find memory_start and
memory_end, simply query memblock_{start,end}_of_DRAM().
Signed-off-by: Mike Rapoport <rppt@linux.ibm.com>
