Subject: [PATCH] sh: migrate to the generic rule for built-in DTB
Date: Sun, 22 Dec 2024 09:32:07 +0900 [thread overview]
Message-ID: <20241222003315.2582655-1-masahiroy@kernel.org> (raw)
Commit 654102df2ac2 ("kbuild: add generic support for built-in boot
DTBs") introduced generic support for built-in DTBs.
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.
