This patch adds support for Seagate BlackArmor NAS220. The Seagate BlackArmor NAS 220 is a NAS system based on Marvell 88f6192. It has 32MB NAND and 128MB DRAM. It has two SATA slots, one Gigabit Ethernet port, two USB 2.0 ports, two buttons and three LEDs. There is a serial port available on the CN5 connector on the board (1 - TX, 4 - RX, 6 - GND). The only functionality still not implemented is the bi-color led on the front panel (status). Pins mpp22 and mpp23 control this led. Setting mpp22 to high and mpp23 to low results in orange color. Setting mpp22 to low and mpp23 to high results in blue color. The third led is wired to show the SATA activity on the two drives.
H Evgeni This is looking good now. I will wait a few days to see if anybody else has any comments, and it not, pull it into mvebu/dt. Thanks Andrew
