MAC addresses (base MFG_MAC from the mfginfo partition; the nvmem
cell index in the DTS is added to the base):

 wan   xx:xx:xx:xx:xx:x0  MFG_MAC
 lan1  xx:xx:xx:xx:xx:x1  MFG_MAC + 0x1
 lan2  xx:xx:xx:xx:xx:x1  MFG_MAC + 0x1
 2.4G  xx:xx:xx:xx:xx:x4  MFG_MAC + 0x4
 5G    xx:xx:xx:xx:xx:xa  MFG_MAC + 0xa
 6G    xx:xx:xx:xx:xx:x6  MFG_MAC + 0x6 (SDG-8732 only)

Both models are also available in versions including 1x FXS POTS
interface for analog phones. Those interfaces are not supported by
OpenWrt.

Installation:

1. Prepare a TFTP server at 192.168.1.10 and serve the OpenWrt
   initramfs image, renamed to "openwrt.<engnum>" for the model
   being installed:

    openwrt.440: SDG-8712
    openwrt.442: SDG-8732

2. Connect to LAN2.
3. Connect to the UART port.
4. Power on the device and type "st" to enter the U-Boot command
   line. The window to do that might be very short (below 1s), so
   type it as soon as the "U-Boot ..." string appears.
5. Run "setenv boot_mode openwrt; saveenv" to boot from OpenWrt
   partition by default.
6. Run "bootmenu" and select option 6 (TFTP openwrt image and
   boot); "run boot5" is a shortcut for the same. This downloads
   openwrt.<engnum> from the TFTP server and boots it.
7. After OpenWrt finishes booting, download the OpenWrt sysupgrade
   image and write it to eMMC using "sysupgrade".
8. After sysupgrade finishes writing, the device reboots into
   OpenWrt. When the front LED is solid white the device is ready
   for configuration.
