ramips: add support for Rakwireless RAK633
It's OEM module with 2*26 pin header, similar to LinkIt Smart 7688 or Vocore2. Specification: CPU: MT7628 580 MHz. MIPS 24K RAM: 64 MB Flash: 8 MB WIFI: 802.11n/g/b 20/40 MHz USB: 1x Port USB 2.0 Ethernet: 5 Port ethernet switch UART: 2x Installation: Use the installed uboot Bootloader. Connect a serial cable to serialport 0. Turn power on. Choose the option: "Load system code then write to Flash via TFTP". Choose the local device IP and the TFTP server IP and the file name of the system image. After if the Bootloader will copy the image to the local flash. Notes: The I2C Kernel module work not correctly. You can send and receive data. But the command i2cdetect doesn’t work. FS#845 Signed-off-by: Eike Feldmann <eike.feldmann@outlook.com> [commit subject and message touches, DTS whitespace fixes, wifi LED rename, pinctrl fixes, network settings fixes, lan/wmac mac addresses, removed i2c kernel modules] Signed-off-by: Petr Štetiar <ynezz@true.cz>
