This add a device tree and build options for the XG6846 switch/router to the BMIPS target. Hardware: - SoC: Broadcom BCM6328 - CPU: BMIPS4350 V7.5 - RAM: 64 MB DDR - NOR Flash: 16 MB parallel (CFE and OS) - Ethernet LAN: 4x 1Gbit - Ethernet WAN: 2x 1Gbit, fiber and TP - Buttons: reset - LEDs: 7 or 8, power and USB LEDs are GPIO-based, the LAN LEDs are controlled by the Marvell DSA Switch. - USB: on some versions - UART: yes It is possible to boot the initramfs version openwrt-bmips-bcm6328-inteno_xg6846-initramfs.elf from CFE by breaking the boot on the UART console and download it from a TFTP server such as: CFE> r 192.168.1.2:openwrt-bmips-bcm6328-inteno_xg6846-initramfs.elf Installation to target flash is not yet possible because the firmware format deviates from the Broadcom standard: it is based on the standard format generated by the "imagetag" tool, but some stuff is off and images don't flash or boot so this needs further work. The Broadcom image creation tool bcmImageBuilder has been patched to take a new command line option such as this: --image-version 4125XG6846_ITT12023725 then this ends up as a string at offset 142-191 in the BCM tag normally used for "rsa-signature" and "information1". There may be other differences as well. We will need to work on this. This device is called a "managed ethernet switch" by the vendor and "media converter" or "fiber modem" by some of the ISPs using it: the main purpose is to convert fiber connections to ethernet, most devices just act as switches bridging the fiber SFP to ethernet TP. The device has a Marvell MV88E6352 DSA switch managed by a BCM6328 BMIPS SoC. This port makes it possible to use the XG6846 to grab an IP number from the fiber connection and use all four LAN connections out, turning it into a proper router. This support is based mostly on the observations by the people on the forum thread "Help with Inteno XG6846" where users NPeca75, mrhaav, systemcrash and csom helped out to reverse engineer the device. Then I made it work on the BMIPS target, figured out the two-level switch hierarchy and settings.
