Similarly this should be "depends on".  To put it more clearly:

- devices that are on a particular bus should "depend on" that bus;

- devices that expose a particular bus (for example a PCI host bridge)
should "select" it so that the user can choose which devices to enable
on that board

- devices can also "select" library features that they use, for example
FRAMEBUFFER or PTIMER, or "sub-devices" that they include, for example
VGA or what you did in I82378

- boards should also "select" devices, but you got that part right so no
need to explain :)
