Subject: [U-Boot] [PATCH 3/3] arm: spear: Disable I2C designware enable status reg check
Date: Wed, 27 Apr 2016 09:10:44 +0200 [thread overview]
Message-ID: <1461741044-30445-3-git-send-email-sr@denx.de> (raw)
In-Reply-To: <1461741044-30445-1-git-send-email-sr@denx.de>
The I2C designware controller doesn't support the enable status register.
This patch disables the check on the SPEAr platforms.
