Subject: [U-Boot] [PATCH 5/9] mmc: remove the unnecessary define and fix the wrong bit control
Date: Thu, 27 Mar 2014 17:54:42 +0900 [thread overview]
Message-ID: <5333E752.30505@samsung.com> (raw)
It's not using anywhere. So it removed the unnecessary define.
And modified the bit operation for more readable.
