Currently USB Host isn't functional on the MPC8315E boards, for two
reasons as described below.
MPC8315 Reference Manual says:
"The USB DR unit must have the same clock ratio as the encryption core
unit, unless one of them has its clock disabled."
The encryption core also drives I2C clock, so it is enabled and is equal
to 01. That means USBDRCM should be 01 here.
Plus, according to MPC8315E-RDB schematics, USB unit consumes CLK_IN
clock from the 24.00MHz oscillator, which means we must adjust REFSEL
bits as well.
p.s.
Idially we should rework whole 83xx/usb.c code, in two steps:
1. Move SCCR code to the U-Boot;
2. Implement fsl,usb-clock property in the device tree, so usb.c could
decide what clock exactly to use on per-board basis.
Though, today we're not in a hurry since there is just one 8315e board
out there.

* Allow multiple boards to be selected in a single build
* Removed Kconfig option '83xx' which existed only for compat with arch/ppc
* Removed Kconfig option 'PPC_MPC836x' since its not used
* Renamed Kconfig option 'MPC834x' to 'PPC_MPC834x' to match others
* Added a multiplatform 83xx defconfig (mpc83xx_defconfig).

Now we're searching for "fsl,qe", "fsl,qe-muram", "fsl,qe-muram-data"
and "fsl,qe-ic".
Unfortunately it's still impossible to remove device_type = "qe"
from the existing device trees because older u-boots are looking for it.

This adds the basic support for the Wind River SBC834x boards. The
SBC8349 is more common, although it should work on the SBC8347 board
as well. Support is heavily based on the existing MPC834x_MDS code.

This patch adds localbus and pata nodes to use CF IDE interface
on MPC8349E-mITX boards.
Patch also adds code to probe localbus.

Remove the declarations for isa_io_base and isa_mem_base as they are declared
in pci-common.c now.

This adds to the 32 bits PCI code some flags, replacing the old
pci_assign_all_busses global, that allow us to control various
aspects of the PCI probing, such as whether to re-assign all
resources or not, or to not try to assign anything at all.
This also adds the flag x86 already has to avoid ISA alignment
on bridges that don't have ISA forwarding enabled (no legacy
devices on the top level bus) and sets it for PowerMacs.

Now the rtc class ds1374 driver has been added, remove the old rtc
driver hookup code, add rtc node to device trees, and turn on the
new driver in the defconfigs.
