 +BCM33xx support was partially introduced in the BCM63xx target. However, the BCM63xx target has been superseded by the BMIPS target, and we lost BCM33xx support (for now).
 +
 +There is a WIP support for BCM3380 on Netgear CG3100D:

 +=== Aeolus ===
 +Cable modems like Netgear CG3100D use a special proprietary bootloader called [[https://github.com/Broadcom/aeolus|Aeolus]]. Broadcom has decided to [[https://github.com/Broadcom/aeolus|open-source the Aeolus implementation for BCM3384]]. Although CG3100D is based on BCM3380, the ProgramStore utility from BCM3384's Aeolus can still be used to prepend necessary headers and compress the OpenWrt firmware image.
 +
 +=== U-Boot ===
 +There is [[https://github.com/u-boot/u-boot/blob/7036abbd5c3934059b020d5fd5bcb8b3bf3c788c/arch/mips/dts/netgear%2Ccg3100d.dts|a U-Boot port for Netgear CG3100D]] by [[https://github.com/Noltari|Noltari]], who's also a core OpenWrt contributor. It only boots in RAM and almost everything (including ethernet and flash) does not work. See [[:inbox:toh:openwrt:netgear_cg3100d_v3]] for how to load it to your device's memory.
