Simon Guinot 3723549695 ARM: add support for Network Space v2 Lite and Mini
This patch adds support for the LaCie boards Network Space v2 (Lite and
Mini). This two boards are derived from the Network Space v2 and a lot
of hardware caracteristics are shared.

- CPU: Marvell 88F6192 800Mhz
- SDRAM memory: 128MB DDR2 200Mhz
- 1 SATA port: internal
- Gigabit ethernet: PHY Marvell 88E1318
- Flash memory: SPI NOR 512KB (Macronix MX25L4005A)
- i2c EEPROM: 512 bytes (24C04 type)
- 2 USB2 ports (Lite only): host and host/device
- 1 push button
- 1 SATA LED (bi-color, blue and red)
