 				Unlike x86 (e.g. Intel/AMD) CPUs, ARM CPUs do not use microcode, not even built in.
 				On the Intel/AMD based libreboot systems, there is still microcode in the CPU
-				(not considered problematic by the FSF, since it's part of the hardware), but we
-				exclude microcode updates, which are proprietary software.

 				On ARM CPUs, the instruction set is implemented in circuitry, without microcode.
