+ Most of these should be rewritten by defining a common interface attribute
+ "foobus", instead of writing multiple attachments. com(4), ld(4), ehci(4)
+ are typical examples. For ehci(4), EHCI-capable controller drivers implement
+ "ehcibus" interface, like:
+
+ defne ehcibus {}
+ device imxehci: ehcibus
+
+ These drivers' attach functions call config_found() to attach ehci(4) via
+ the "ehcibus" interface attribute, instead of calling ehci_init() directly.
+ Same for com(4) (com_attach_subr()) and ld(4) (ldattach()).
