Subject: [OpenRISC] [PATCH 08/15] mircoblaze: drop unneeded NUMA and sparsemem initializations
Date: Tue, 28 Jul 2020 05:13:34 -0000 [thread overview]
Message-ID: <20200728051153.1590-9-rppt@kernel.org> (raw)
In-Reply-To: <20200728051153.1590-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
microblaze does not support neither NUMA not SPARSMEM, so there is no point
to call memblock_set_node() and sparse_memory_present_with_active_regions()
functions during microblaze memory initialization.
Remove these calls and the surrounding code.
