[Tested successfully] Linux on Arduino UNO / atmega328p port of mini-rv32ima. Let's run Linux on the world's worst Linux PC (and beat Dmitry Grinberg)
The binary is for atmega328p @ 16MHz
This release added icache and other cache stuff, for x2 - x3 speed while reducing read/write cycle to/from SD card.
The HEX is for atmega328p running at 16MHz. UART baudrate is 9600 bps.
