Subject: [PATCH 08/15] ARC: migrate to the generic rule for built-in DTB
Date: Thu, 5 Sep 2024 08:47:44 +0900 [thread overview]
Message-ID: <20240904234803.698424-9-masahiroy@kernel.org> (raw)
In-Reply-To: <20240904234803.698424-1-masahiroy@kernel.org>
Select GENERIC_BUILTIN_DTB to use the generic rule to support built-in
DTB.
To keep consistency across architectures, this commit also renames
CONFIG_ARC_BUILTIN_DTB_NAME to CONFIG_BUILTIN_DTB_NAME.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
