- common USB code
-
-This patch updates the common USB code touching the USB private
-registers with the specific bits to properly enable OHCI and EHCI
-controllers on BCM63xx SoCs. As a result we now need to protect access
-to Read Modify Write sequences using a spinlock because we cannot
-guarantee that any of the exposed helper will not be called
-concurrently.

- symbol
-
-This configuration symbol can be used by CPUs supporting the on-chip
-OHCI controller, and ensures that all relevant OHCI-related
-configuration options are correctly selected. So far, OHCI support is
-available for the 6328, 6348, 6358 and 6358 SoCs.

+Instead of treating each flavour as an exclusive CPU to select, make
+BMIPS the only option and let SYS_HAS_CPU_BMIPS* decide for which
+flavours to include support.
+
+Run tested on BMIPS3300 and BMIPS4350, only build tested for BMIPS4380

- controller
-
-Broadcom BCM63XX SoCs include an on-chip OHCI controller which can be
-driven by the ohci-platform generic driver by using specific power
-on/off/suspend callback to manage clocks and hardware specific
-configuration.

- controller
-
-Broadcom BCM63XX SoCs include an on-chip EHCI controller which can be
-driven by the generic ehci-platform driver by using specific power
-on/off/suspend callbacks to manage clocks and hardware specific
-configuration.

+
+This patch moves the code touching the USB private register in the
+bcm63xx USB gadget driver to arch/mips/bcm63xx/usb-common.c in
+preparation for adding support for OHCI and EHCI host controllers which
+will also touch the USB private register.

+This patch updates the common USB code touching the USB private

+to Read Modify Write sequences using a spinlock because we cannot
+guarantee that any of the exposed helper will not be called
+concurrently.
