Note that 68360 support was removed from the kernel in 2016, as Arnd said. > > Anyone working on integrating m68k (and SPARC and MIPS?) softcores in > > LiteX? ;-) > > I'm personally waiting for the Vampire to gain support for the real 68851 > as the hardware in general looks very attractive [1]. The 68851 is way too complex for what's needed (who needs support for 256 byte pages (https://lwn.net/Articles/839746/)?). They'd be better off implementing something simpler, like 68040 MMU support, or perhaps even a software-controlled TLB like most RISC architectures (incl. ColdFire?). The latter would require more changes to Linux, though.
