Subject: [PATCH v3 10/10] ARM:stih41x: Add B2020 board support
Date: Thu, 20 Jun 2013 15:07:03 +0100	[thread overview]
Message-ID: <1371737223-9650-1-git-send-email-srinivas.kandagatla@st.com> (raw)
In-Reply-To: <1371736996-8770-1-git-send-email-srinivas.kandagatla@st.com>

B2020 ADI board is reference board for STIH415/416 SOCs, it has 2 x
UART, 4x USB, 1 x Ethernet, 1 x SATA, 1 x PCIe, and 2GB RAM  with
standard set-top box IPs.

This patch adds initial support to B2020 with STiH415/416 with SBC_UART1
as console and a heard beat LED.
