[U-Boot] [PATCH 26/30] env: Drop env_get_char_spec()

From: Simon Glass <sjg@chromium.org>

Subject: [U-Boot] [PATCH 26/30] env: Drop env_get_char_spec()
Date: Sun,  9 Jul 2017 14:53:09 -0600	[thread overview]
Message-ID: <20170709205313.116174-27-sjg@chromium.org> (raw)
In-Reply-To: <20170709205313.116174-1-sjg@chromium.org>

We only have a single implementation of this function now and it is called
env_get_char(). Drop the old function and the weak version.
