No MMU, plain m68k code. 68328 Soc = 68000 core + some peripherals, 68360 SoC = CPU32 core (based on 68020 + some peripherals. Anyone working on integrating m68k (and SPARC and MIPS?) softcores in LiteX? ;-) Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux-m68k.org In personal conversations with technical people, I call myself a hacker.
