Subject: [U-Boot] [PATCH 06/11] st_smi: Read status until timeout happens
Date: Fri, 24 Feb 2012 17:53:09 +0530	[thread overview]
Message-ID: <1330086194-21762-7-git-send-email-amit.virdi@st.com> (raw)
In-Reply-To: <1330086194-21762-1-git-send-email-amit.virdi@st.com>

From: Vipin KUMAR <vipin.kumar@st.com>

SMI driver read status fails because the control register could not be
overwritten. Instead, the read status should be tried until timeout.
