         | The Pi5 southbridge was codenamed RP1, the RP2040 was RP2, and
         | the RP2350 is apparently RP4.
         | 
         | What might RP3 be I wonder? Not necessarily another
         | microcontroller, given that RP1 wasn't one.

         | A question was asked at this year's DEF CON during the "Making
         | The DEF CON 32 Badge" talk. Luke Wren responded by saying he
         | couldn't compare size of the ARM and RISC-V cores, but said
         | that taking them out wouldn't make the chip die smaller. He
         | added that he knew exactly what shape hole the core was going
         | to fit into, and designed it to fit.
