Subject: [PATCH 12/15] sh: migrate to the generic rule for built-in DTB
Date: Thu, 5 Sep 2024 08:47:48 +0900 [thread overview]
Message-ID: <20240904234803.698424-13-masahiroy@kernel.org> (raw)
In-Reply-To: <20240904234803.698424-1-masahiroy@kernel.org>
Select GENERIC_BUILTIN_DTB when built-in DTB support is enabled.
To keep consistency across architectures, this commit also renames
CONFIG_USE_BUILTIN_DTB to CONFIG_BUILTIN_DTB, and
CONFIG_BUILTIN_DTB_SOURCE to CONFIG_BUILTIN_DTB_NAME.
