target/linux/ixp4xx/patches/050-dsmg600_upstream_support.patch

   1 This patch adds support for the D-Link DSM-G600 Rev A.
   2 This is an ARM XScale IXP4xx system relatively similar to
   3 the NSLU2 and NAS-100D already supported by mainline. An
   4 important difference is Gigabit Ethernet support using
   5 the Via Velocity chipset.
   6
   7 This patch is the combined work of Michael Westerhof and
   8 Alessandro Zummo, with contributions from Michael-Luke
   9 Jones. This version addresses review comments from rmk
  10 and Deepak Saxena.
