No problem have a look at it when you find some time for it. There are still some todos and the serial flash chip is also on my list, so I will not run out of stuff to do. ;-) > >> An Ethernet driver is not included because the Braodcom source code >> available is not licensed under a GPL compatible license and building a >> new driver on that based is not possible. > > I wonder if you could write specs for that core, so I could write > GPL/any driver for it?

Henry Ptasinski from Broadcom wanted to make it possible for us to use the Braodcom driver directly as a base, but talking to all the lawyers and managers at Braodcom to make this possible takes a lot of time and is not promising. After this and flash support is in the kernel I will work on the Ethernet driver. The driver is not really big so it will not take that long to write a spec and implement it. I published my git repo with the modifications integrated into OpenWrt: https://github.com/hauke/openwrt/tree/bcma-list Hauke
