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) Signed-off-by: Simon Guinot <simon.guinot@sequanux.org>
