Subject: [PATCH v7 18/33] arm64: kernel: Remove early fdt remap code
Date: Fri, 11 Nov 2022 18:11:46 +0100 [thread overview]
Message-ID: <20221111171201.2088501-19-ardb@kernel.org> (raw)
In-Reply-To: <20221111171201.2088501-1-ardb@kernel.org>
The early FDT remap code is no longer used so let's drop it.
