Prior to Zen based processors there are a decent number of offerings under the Opteron and AMD's embedded SoC families (possibly others, but these are the ones I'm familiar with) which did not contain ME-like capabilities. Projects like Coreboot generally have pretty good support for these AMD parts. For an embedded example, see the PCEngines APU2 boards: http://pcengines.ch/apu2.htm http://pcengines.ch/apu2.htm Zen based parts from AMD have their PSP (platform security processor), which I believe is generally a dedicated Cortex-A series CPU within the silicon to do many security related things. Its functionality is similar to some of what the ME provides on Intel parts.
