Debian is still kind enough to provide an ARMv4t and higher port (ArmEabi) though I am not sure how long this is going to stay that way. > >> The port is not near mainline but I think I'd prefer if CPU_FA526 >> wasn't removed.

Imre Kaloz is supposed to have some, if you want to get some hardware yourself it seems that the mainline boards (WBD111, WBD222, NAS4420) are the only hardware devices that OpenWrt also supports. The OpenWrt patches we have add support for Ethernet, watchdog, USB, PCI, but have not been submitted mainline. > > My plan right now is to leave CPU_FA526 alone but drop ARCH_GEMINI > in 3.10.
