How would that fit into this naming scheme? > Would it be a different MACH? Rocket is a 64-bit core, VexRiscv is a 32-bit core. All LiteX family SoC use the same peripheral IP cores, but different CPU cores. The situation is similar to MIPS Malta FPGA devboard, main FPGA can be burned with very different CPU bitstreams: config MIPS_MALTA bool "MIPS Malta board" ... select SYS_HAS_CPU_MIPS32_R1 select SYS_HAS_CPU_MIPS32_R2 select SYS_HAS_CPU_MIPS32_R3_5 select SYS_HAS_CPU_MIPS32_R5 select SYS_HAS_CPU_MIPS32_R6 select SYS_HAS_CPU_MIPS64_R1 select SYS_HAS_CPU_MIPS64_R2 select SYS_HAS_CPU_MIPS64_R6 select SYS_HAS_CPU_NEVADA select SYS_HAS_CPU_RM7000 I'll investigate the problem more carefully.
