e85477f516 powerpc/83xx: Fix TSEC0 workability on MPC8313E-RDB boards
TSEC0 is connected to Vitesse 7385 5-port switch. The switch
isn't connected to any mdio bus, the link to the switch is fixed
to Full-duplex 1000 Mb/s (no pause).

This patch fixes following failure during bootup:

mdio@24520:01 not found
eth0: Could not attach to PHY
IP-Config: Failed to open eth0

commit b31a1d8b41 ("gianfar: Convert

6c9789de2a powerpc/83xx: Make serial ports work on MPC8315E-RDB w/ FSL U-Boots
FSL U-Boots use /soc8315@e0000000 node to search and fixup serial
nodes' clock-frequency properties. Though in upstream kernels we use
new naming convention -- for IMMR address space dts files specify
/immr@e0000000 nodes.

This makes FSL U-Boots fail to fixup the clock frequencies, and that
leads to serial ports misbehaviour. We can workaround the issue by
filling the clock frequency values manually.

p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for
ethernet nodes, so users should either change the .dts file locally
or set MAC address via `ifconfig hw ether' command.

6ec9eae67a [WATCHDOG] Enable watchdog timer on GE Fanuc's SBC610
Support for the FPGA based watchdog timer on GE Fanuc's SBC610.

This patch enables one of the watchdog timers found on the SBC610. There are
two identical watchdog timers at different offsets in the above mentioned
boards, however the current driver is only capable of supporting one of them.

The watchdog timers are also capable of generating interrupts at a
user-configurable threshold, though support for this operation is currently
not supported by the driver.

29f1aff2cc powerpc: Copy bootable images in the default install script
This patch makes the default install script (arch/powerpc/boot/install.sh)
copy the bootable image files into the install directory.  Before this
patch only the vmlinux image file was copied.

This patch makes the default 'make install' command useful for embedded
development when $(INSTALL_PATH) is set in the environment.

As a side effect, this patch changes the calling convention of the
install.sh script.  Instead of a single 5th parameter, the script is now
passed a list of all the target images stored in the $(image-y) Makefile
variable.  This should be backwards compatible with existing install scripts
since it just adds additional arguments and does not change existing ones.

796bcae736 USB: powerpc: Workaround for the PPC440EPX USBH_23 errata [take 3]
A published errata for ppc440epx states, that when running Linux with
both EHCI and OHCI modules loaded, the EHCI module experiences a fatal
error when a high-speed device is connected to the USB2.0, and
functions normally if OHCI module is not loaded.

There used to be recommendation to use only hi-speed or full-speed
devices with specific conditions, when respective module was unloaded.
Later, it was observed that ohci suspend is enough to keep things
going, and it was turned into workaround, as explained below.

Quote from original descriprion:

The 440EPx USB 2.0 Host controller is an EHCI compliant controller.  In
USB 2.0 Host controllers, each EHCI controller has one or more companion
controllers, which may be OHCI or UHCI.  An USB 2.0 Host controller will
contain one or more ports.  For each port, only one of the controllers
is connected at any one time. In the 440EPx, there is only one OHCI
companion controller, and only one USB 2.0 Host port.
All ports on an USB 2.0 controller default to the companion
controller.  If you load only an ohci driver, it will have control of
the ports and any deviceplugged in will operate, although high speed
devices will be forced to operate at full speed.  When an ehci driver
is loaded, it explicitly takes control of the ports.  If there is a
device connected, and / or every time there is a new device connected,
the ehci driver determines if the device is high speed or not.  If it
is high speed, the driver retains control of the port.  If it is not,
the driver explicitly gives the companion controller control of the
port.

The is a software workaround that uses
Initial version of the software workaround was posted to
linux-usb-devel:

http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg54019.html

and later available from amcc.com:
http://www.amcc.com/Embedded/Downloads/download.html?cat=1&family=15&ins=2

The patch below is generally based on the latter, but reworked to
powerpc/of_device USB drivers, and uses a few devicetree inquiries to
get rid of (some) hardcoded defines.

The newest revision of uboot reworks the memory map for this
board to look more like the 85xx boards.  Also, some regions
which were far larger than the actual hardware have been scaled
back to match the board, and the imaginary second flash bank has
been removed. Rapidio and PCI are mutually exclusive in the hardware,
and they now are occupying the same space in the address map.
The Rapidio node is commented out of the .dts since PCI is the
common use case.

5663a1232b Revert "powerpc: Sync RPA note in zImage with kernel's RPA note"
This reverts commit 91a0030295, plus
commit 0dcd440120 ("powerpc: Revert CHRP
boot wrapper to real-base = 12MB on 32-bit") which depended on it.

Commit 91a00302 was causing NVRAM corruption on some pSeries machines,
for as-yet unknown reasons, so this reverts it until the cause is
identified.

2dccbf4ea0 powerpc: Fix bug in kernel copy of libfdt's fdt_subnode_offset_namelen()
There's currently an off-by-one bug in fdt_subnode_offset_namelen()
which causes it to keep searching after it's finished the subnodes of
the given parent, and into the subnodes of siblings of the original
node which come after it in the tree.  This bug was introduced in
commit ed95d7450d ("powerpc: Update
in-kernel dtc and libfdt to version 1.2.0").

A patch has already been submitted to dtc/libfdt mainline.  We don't
really want to pull in a new upstream version during the 2.6.28 cycle,
but we should still fix this bug, hence this standalone version of the
fix for the in-kernel libfdt.

71773f0337 powerpc: Add del_node() for early boot code to prune inapplicable devices.
Some platforms have variants that can share most of a flat device tree but need
a few devices selectively pruned at boot time.  This adds del_node() to ops.h
to allow access to the existing fdt_del_node().
