Because option dependencies are done as a separate pass after parsing the config file, what I’ll need to do is keep track of every option explicitly de-selected in the config file with a “no option” statement, and then consult that table when processing the depended-options.

Ok, that was pretty straightforward:

<snip>
# CPU support.  At least one is REQUIRED.
options         M68060
options         M68040
options         M68030
options         M68020          # Note:  must have 68851 PMMU

# CPU-related options.
options         FPU_EMULATE
no options      FPSP
no options      M060SP
