After looking at various vendor GPL source code dumps I discovered that some of them contain updated versions of ltq-ptm driver when compared to what openwrt has. The driver update is mostly cursory (simple changes to comments, whitespace, formatting etc.) or adds debug features not used by openwrt. However the updated driver also contains a later version of PTM firmware which is extracted and included in this commit along with bits to correctly identify its version when driver loads.
