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:

commit b31a1d8b41513b96e9c7ec2f68c5734cef0b26a4 ("gianfar: Convert

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.Signed-off-by: Anton Vorontsov

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.Signed-off-by: Martyn Welch

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.Signed-off-by: Grant Likely

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

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.Signed-off-by: Becky Bruce

Since the QPACE (Chromodynamics Parallel Computing on the
Cell Broadband Engine) platform doesn't use a iommu, doesn't
have PCI devices and a MPIC much lesser setup and
configurations are needed. So far all devices are detected
as OF device. A notifier function is used to set the dma_ops
for the of_platform bus. Further this patch splits the
PPC_CELL_NATIVE into PPC_CELL_COMMON which are parts that are
shared with the QPACE platform and the rest.Signed-off-by: Benjamin Krill

With this patch the L2 cache is enabled on Canyonlands to increase the
overall performance. There is a known cache coherency issue with the L2
cache, but this is related to the high bandwidth (HB) PLB segment where
the memory address is 0x8.xxxx.xxxx (low bandwidth PLB segment is mapped
to 0x0.xxxx.xxxx). Since this HB address is currently unused it is safe
to enable the L2 cache.Signed-off-by: Stefan Roese

This adds support for ISA memory holes on the PCI, PCI-X and
PCI-E busses of the 4xx platforms. The patch includes changes
to the Bamboo and Canyonlands device-trees to add such a hole,
others can be updated separately.The ISA memory hole is an additional outbound window configured
in the bridge to generate PCI cycles in the low memory addresses,
thus allowing to access things such as the hard-decoded VGA
aperture at 0xa0000..0xbffff or other similar things. It's made
accessible to userspace via the new legacy_mem file in sysfs for
which support was added by a previous patch.Signed-off-by: Benjamin Herrenschmidt

("powerpc/83xx: Add support for MCU microcontroller in .dts files"):
the commit adds the MCU controller node into the DMA node, which is
wrong because the MCU sits on the I2C bus. Fix this by moving the MCU
node into the I2C controller node.The original patch[1] was OK though. ;-)
