ARM946E-S is used in the DIGIC family SoCs.
ARM946E-S core supports ARMv5TE and has Cache & MPU.
Linux kernel uses ARMv4 MPU cache routines for ARM946E-S core.
E.g. see linux.git/boot/compressed/head.S:
.word 0x41009400 @ ARM94x
.word 0xff00ff00
W(b) __armv4_mpu_cache_on
W(b) __armv4_mpu_cache_off
W(b) __armv4_mpu_cache_flush
So select CPU_32v4T for ARM946E-S despite of ARMv5TE support.

USB core isn't too strict about allocation/deallocation and
add/remove sequences of usb devices. Especially, error paths
and device tear-down are kind of broken and cause hangs on
failing usb device detect.
This patch improves the situation by introducing a
usb_free_device() that tears down allocated resources by
usb_alloc_new_device(). usb_remove_device() now only deals
with resources that have been added by usb_new_device().
Also, error handling is fixed or improved to ensure that no
devices are unregistered that have not been previously
registered.

Adding a usb device increases dev_index every time a new device is
allocated. Removing a usb device does not decrease again, of course.
As we print the number of detected usb devices after each usb bus
scan based on dev_index, we cannot trust dev_index here. Keep track
of the correct number of (currently) detected usb devices by
introducing an independent dev_count that gets increased on detect
and decreased on remove.

On Marvell MVEBU SoCs internal registers are usually remapped from reset
default. While Dove and Kirkwood always had their registers remapped,
some Armada 370 and XP where shipped with bootloaders that did not remap
them.
On Barebox these registers are remapped early and on all MVEBU SoCs, so
provided DTs should always reflect that in their mbus ranges property.
This patch registers a fixup for DTBs and allows individual SoCs to add
specific remap ranges to the fixup list. The fixup is registered on
pure_initcall to even allow to fixup pbl or appended DTBs.
