1.
root_complex
pci_domain
NB
SB
End
End
Apic
End
Is more understanding even for one MC MB.
2.
Without " config chip.h"
The corresponding device chip_ops field will be 0, and not to some ......ops
(all zero).
3. another is
if not define " uses CONFIG_CHIP_NAME" in MB Option.lb
and use "if CONFIG_CHIP_NAME config chip.h end
the config.g will be report CONFIG_CHIP_NAME is not defined, just
some other strang reporting.

Could we please reserve this construct for chipsets
with multiple northbridges?
I think it is just going to be extra noise on a
simple chipset like the e7501.
And since the e7501 is an example to a certain extent having it
doing extra work be confusing and a pain.

They can. But I am about to suggest simply removing the config
directive, and assuming the ``config chip.h'' is always given. The
overhead is almost zero for a zero filled structure. And always
requiring a chip.h would tend to simply the process of writing code
for a new chip.
