   Pimoroni Pico plus 2 is sitting on my desktop ready for me to play with   
   it.    
      
   This beast also has 16MB of flashram and 8MB of PSRAM. I've also got a   
   SD card board and some headers I need to solder on to use with it.    
      
   I've got a RISCV baremetal operating system I might bring up on this   
   device but looking at the datasheet for the RISCV processor used, it's   
   only got machine mode and user mode, no supervisor mode and no paging.   
   It does not even support any of the Sv pagetables so that's a   
   challenge.    
      
   Most interestingly enough, you can actually boot up with one RISCV core   
   and one ARM core, two RISCV cores or both ARM cores. Mixed processor   
   cores that'll be fun to see what we can do with that.
