I think the recursion should also be limited to cases where the
dependency is a valid selectable option, i.e. not for
# this architecture does not support MMIO
config HAS_IOMEM
def_bool 'n'
config PCI
bool "PCI Device drivers"
depends on HAS_IOMEM
config FOO
tristate "Some device driver"
depends on PCI
In this case, it would be straightforward for the solver to enable PCI
for when something selects CONFIG_FOO, but it should print a warning
if this is attempted while HAS_IOMEM is unconditionally disabled,
since that puts it into the "not simple" category.
