Subject: [PATCH AUTOSEL 5.16 11/28] of/fdt: move elfcorehdr reservation early for crash dump kernel
Date: Tue,  1 Mar 2022 15:13:16 -0500	[thread overview]
Message-ID: <20220301201344.18191-11-sashal@kernel.org> (raw)
In-Reply-To: <20220301201344.18191-1-sashal@kernel.org>

From: Nikhil Gupta <nikhil.gupta@nxp.com>

[ Upstream commit 132507ed04ce0c5559be04dd378fec4f3bbc00e8 ]

elfcorehdr_addr is fixed address passed to Second kernel which may be conflicted
with potential reserved memory in Second kernel,so fdt_reserve_elfcorehdr() ahead
of fdt_init_reserved_mem() can relieve this situation.
