Hi!
From: Lukas Bulwahn <lukas.bulwahn@xxxxxxxxx>
[ Upstream commit b0100bce4ff82ec1ccd3c1f3d339fd2df6a81784 ]
Since commit 4b563a066611 ("ARM: imx: Remove imx21 support"), the config
DEBUG_IMX21_IMX27_UART is really only debug support for IMX27.
This is unsuitable for 4.4 as imx21 is still supported there.
