SMVP) for the MIPS_CMP (ie. CMP framework support) Kconfig option. It did not specify why, and that dependency is bogus. It is perfectly valid to have a multi-core system with the YAMON bootloader but without MT support - an example of this would be any multi-core proAptiv bitstream running on a Malta. Forcing MT support to be enabled in a kernel for such a system is incorrect. I suspect that the dependency was actually meant to reflect the fact that YAMON will only bind 1 TC per VPE on an MT system, and only describe those 1:1 TC:VPE pairs as CPUs through the AMON interface. Thus an SMTC kernel makes little sense on a system using MIPS_CMP, and the Kconfig dependencies should reflect that rather than introducing the bogus SMVP dependency.
