Subject: [PATCH 05/23] serial: Add a SERIAL config
Date: Sun,  8 Aug 2021 12:20:13 -0600	[thread overview]
Message-ID: <20210808182031.3747270-6-sjg@chromium.org> (raw)
In-Reply-To: <20210808182031.3747270-1-sjg@chromium.org>

At present we have SPL_SERIAL and TPL_SERIAL but not piain SERIAL. This
works because there is a special build rule in Makefile that always
includes the drivers/serial directory.

It is better to have all driver directories included by drivers/Makefile
and there is already a rule in there for this purpose. It just needs a
Kconfig for U-Boot proper, so add one.

It is always enabled, for now, since that mimics the current behaviour.
It should be possible to drop the strange 'SERIAL_PRESENT' option at some
point and use SERIAL instead.
