Openwrt/target/linux/brcm47xx-2.6/patches/120-b44_ssb_support.patch
Felix Fietkau b266b01045 Add initial version of the brcm-2.6 rewrite, called brcm47xx-2.6 to better distinguish it from 63xx. 
Boots on WGT643U, includes ethernet support, but doesn't do much otherwise.
Thanks to Michael Buesch for his SSB (Sonics SiliconBackplane) work
and Vladdy for some fixes and porting to 2.6.19.
