Documentation

The new-style revision code is a result of a 32 bit value, (almost) each bit represents a piece of hardware-information: NOQuuuWuFMMMCCCCPPPPTTTTTTTTRRRR

N O Q uuu W u F MMM CCCC PPPP TTTTTTTT RRRR
Overvoltage OTP Program OTP Read Unused Warranty bit Unused New flag Memory size Manufacturer Processor Type Revision

For identification the first 24 bit are needed.
With cat /proc/cpuinfo | grep "Revision" the revision code is read out.

The official, but incomplete documentation is located here.
