mvebu: add support for IIJ SA-W2 Internet Initiative Japan Inc. (IIJ) SA-W2 is a network appliance with 11ac (Wi-Fi 5) wlan, based on 88F6810. Specification: - SoC  : Marvell Armada 380 88F6810 - RAM  : DDR3 256 MiB (Micron MT41K64M16TW-107:J x2) - Flash  : SPI-NOR 32 MiB (Winbond W25Q256JVFIQ) - WLAN  : 2.4/5 GHz, Mini PCI-E - 2.4 GHz  : Silex SX-PCEGN (Atheros AR9287 (2T2R)) - 5 GHz  : Silex SX-PCEAC (Qualcomm Atheros QCA9880 (3T3R)) - Ethernet  : 10/100/1000 Mbps x5 - Switch  : Marvell 88E6172 - LEDs/Keys  : 12x/1x - UART  : "CONSOLE" port (RJ-45, RS-232C) - settings  : 115200n8 - assignment: 1:NC, 2:NC, 3:TXD, 4:GND, 5:GND, 6:RXD, 7:NC, 8:NC - note  : compatible with Cisco console cable - Power  : DC Input or PoE - DC Input  : 12 VDC, 3 A - PoE  : 802.3af - module  : Silvertel Ag9712-2BR - note  : USB ports shouldn't be used when powered by PoE - Bootloader  : PMON2000 based - Stock  : NetBSD based Flash instruction using sysupgrade image: 1. Prepare TFTP server with IP address 192.168.0.10 and put sysupgrade image to TFTP directory 2. Connect PC to "GE0/PoE" port on SA-W2 3. Power on SA-W2, interrupt count-down by Esc and enter to bootloader CLI 4. Set IP address of the device address 192.168.0.1 5. Download sysupgrade image and flash to storage tftpload 192.168.0.10 <image name> firmwrite example: #tftpload 192.168.0.10 openwrt-mvebu-cortexa9-iij_sa-w2-squashfs-sysupgrade.bin Loading openwrt-mvebu-cortexa9-iij_sa-w2-squashfs-sysupgrade.bin loaded 8127268 byte(s) #firmwrite Erasing FLASH block 32 Done 0x00200000.

Boot with the flashed firmware boot Note: - The bootloader on this device is not U-Boot and it's environment space ("bootloader-env") has no compatibility with U-Boot tools. - eth1 is connected to port6 of 88E6172 switch, but multi-cpu port can't be handled on Linux Kernel and not defined. - Powering by PoE hasn't been tested yet. - This device has 2x OS images on flash and they can be switched by setting "BOOTDEV" variable on bootloader CLI. That variable supports the following values: - "flash" : primary image on flash ("firmware") - "rescue": secondary image on flash ("rescue") - "usb"  : usb storage (broken?) - "lan0/1": network command to set: set BOOTDEV=<dev> example: set BOOTDEV=rescue This commit also supports booting from secondary partition. - To execute initramfs image on bootloader CLI, use "go" command. ("go" command is not listed on the output of "help", but available) example (download and execute): address 192.168.0.1 tftpload 192.168.0.10 openwrt-mvebu-cortexa9-iij_sa-w2-initramfs-kernel.bin go MAC addresses: LAN  : 00:E0:4D:xx:xx:19 (none) WAN  : 00:E0:4D:xx:xx:18 (board_info, 0x6 (hex)) 2.4 GHz: 84:25:3F:xx:xx:xx (Mini PCI-E card) 5 GHz  : 84:25:3F:xx:xx:xx (Mini PCI-E card)
