Subject: [PATCH v6 4/5] spl: Allow SPL/TPL to use of-platdata without libfdt
Date: Sun, 25 Jul 2021 10:13:46 -0600	[thread overview]
Message-ID: <20210725161347.457937-5-sjg@chromium.org> (raw)
In-Reply-To: <20210725161347.457937-1-sjg@chromium.org>

At present libfdt is included in SPL/TPL if SPL/TPL_OF_CONTROL is enabled.
But if of-platdata is in use this is not required. Update the condition to
avoid building this extra code. This ensures that if a libfdt function is
used it will produce a link error rather than silently increasing the
build size.
