Stuff TODO.

The intent of Patina is to replace blinky in amaranth. Given (most; LUT > 0x1000), drop a riscv32i control plane CPU. This means that we can put a software state machine upon it.

The base is minimual rust but if you insist on writing C++ or C that will work aswell.

There appears to be a lot of stuff to do. My brain has stalled, so I should probably write a list.

Gateware

Firmware

1. fix print! and println! , rework.
2. Rewrite the simple fabric to a multiplexer
3. write an amaranth_soc <-> hapenny bus bridge.
4. look into the svd exporter (for embeded-hal)
5. auto generate bootloader
6. move the command line into patina/cli.py
7. move the logging builder into patina/logging.py
8. clean up the flash lib
   1. add u32 reader and iterator
