Subject: [PATCH 2/4] ARM: sirf: add atlas7 machine support
Date: Thu, 25 Dec 2014 16:34:18 +0800	[thread overview]
Message-ID: <1419496460-4929-3-git-send-email-21cnbao@gmail.com> (raw)
In-Reply-To: <1419496460-4929-1-git-send-email-21cnbao@gmail.com>

From: Zhiwu Song <Zhiwu.Song@csr.com>

atlas7 is next-gen auto soc from CSR.
It could bring to customers most integrated SoC solution:
- World leading Bluetooth 4.0 and GNSS baseband
- Audio processing, analog CODEC and ADC
- Analog video input
- SDR accelerators
