[PATCH 2/4] ARM: sirf: add atlas7 machine support

[21cnbao@gmail.com (Barry Song)]

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
