This new usb driver uses an extra device so the ehci and the ohci driver are not depending on ech other any more.

+Subject: [PATCH 15/21] bcma: scan for extra address space
+
+Some cores like the USB core have two address spaces. In the USB host
+controller one address space is used for the OHCI and the other for the
+EHCI controller interface. The USB controller is the only core I found
+with two address spaces. This code is based on the AI scan function
+ai_scan() in shared/aiutils.c i the Broadcom SDK.

+It is used in bcma_core_set_clockmode() and bcma_core_pll_ctl() to
