SB700 mainboard support seems copypasted rather than engineered. The
sustainable solution is to move sb700_cfg.c from src/mainboard/*/
to src/southbridge/amd/cimx/sb700/ and hook the configuration in that
file into Kconfig.

Until someone does that, you could indeed change the assignment of
that option by looking for


in the source code, if a sb700_cimx_config() function is called for
this board - but that might not be the case if the board port chose
not to use that part of AGESA.
