The prior help text introduced in commit f55afb0969cc "MIPS: Clean up MIPS MT and CMP configuration options." reads as though this option enables the kernel to make use of the CM hardware, which is not true. What it actually does is allow the kernel to interact with the YAMON bootloader which actually interacts with the CM hardware to bring up secondary cores. Re-introduce the word "framework" which that commit removed to avoid misleading people.
