Daniel González Cabanelas 85ef69b202 mvebu: add support for Buffalo LinkStation LS421DE ... Buffalo LinkStation LS421DE is a dual bay NAS, based on Marvell Armada 370 Hardware: SoC: Marvell Armada 88F6707-A1 CPU: Cortex-A9 1200 MHz, 1 core Flash: SPI-NOR 1 MiB, NAND 512 MiB RAM: DDR3 512 MiB Ethernet: 1x 10/100/1000 Mbps USB: 1x 2.0, 1x 3.0 SATA: 2x 3.0 Gbps LEDs/Input : 5x / 2x (1x button, 1x slide-switch) RTC: Ricoh RS5C372A, I2C, no battery Flash instruction (UART+TFTP): 1. Downgrade the OEM firmware to 1.34 version (BUFFALO_BOOTVER=0.13) 2. Remove any hard drive from inside the bays. 3. Boot the Openwrt initramfs image using the U-Boot serial console: tftpboot 0x1200000 buffalo_ls421de-initramfs-kernel.bin bootm 0x1200000 4. Flash the sysupgrade image using the Openwrt console: sysupgrade -n buffalo_ls421de-squashfs-sysupgrade.bin 5. Wait until it finish, the device will reboot with Openwrt installed on the NAND flash. Note: - Device shuting down doesn't work, even if the power slide switch is used. We must first, via MDIO, set the unused LED2 at the ethernet phy0 to off state. Reboot works ok.
