Subject: [U-Boot] [PATCH v7 2/6] spi: cadence_qspi: fix indirect read/write start address
Date: Wed, 23 Sep 2015 17:19:32 -0700	[thread overview]
Message-ID: <1443053976-9112-3-git-send-email-vikas.manocha@st.com> (raw)
In-Reply-To: <1443053976-9112-1-git-send-email-vikas.manocha@st.com>

Indirect read/write start addresses are flash start addresses for indirect read
or write transfers. These should be absolute flash addresses instead of
offsets.
