Subject: [PATCH v7 12/50] arm64: kernel: Remove early fdt remap code
Date: Tue, 23 Jan 2024 15:53:11 +0100 [thread overview]
Message-ID: <20240123145258.1462979-64-ardb+git@google.com> (raw)
In-Reply-To: <20240123145258.1462979-52-ardb+git@google.com>
From: Ard Biesheuvel <ardb@kernel.org>
The early FDT remap code is no longer used so let's drop it.
