Add a phy_type field to the tsi108 ethernet structures to indicate which PHY
is used on a board.  This is derived from the "compatible" property in the
ethernet-phy node of the device tree.  The default remains the MV88E PHY.

Also, convert the setup code to use of_get_mac_address instead of hard coding
a lookup for the "address" property in the ethernet node.

The generic LED code now makes sure that suspended devices don't blink,
so we no longer need to do it ourselves. For the suspend to disk case,
however, we need to make sure that we don't blink if the PMU sysdev
was suspended before the LED device.

Currently our code to set up the data structures for a PCI host bridge
and create the mapping for its I/O window assumes that the window
starts at I/O port 0 on the PCI side.  If this is not true, we can end
up with I/O port numbers in the resources for PCI devices which will
cause an oops if a driver tries to access them via inb/outb etc.,
because there is no mapping for the corresponding addresses.

Normally the I/O window starts at 0, but there are some situations on
partitioned machines with a hypervisor where the window may not start
at 0.

This fixes the problem by allocating space for the range from 0 to the
end of the I/O window.  That is, hose->io_base_virt contains the
virtual address for I/O port 0 on the PCI bus, and thus the assumption
that hose->io_base_virt - pci_io_base is the offset between the
"global" I/O port numbers (those in the PCI device resources) and the
I/O port numbers on the PCI bus is maintained.

For PCI host bridges that are present at boot, we only map the portion
of that range that correspond to the bridge's I/O window.  For bridges
added after boot we ioremap the range from 0 to the end of the I/O
window, for now; in fact hot-added bridges should be using
reserve_phb_iospace() and __ioremap_explicit (so they get sensible
global port numbers), but we don't have the infrastructure yet to do
that (basically a free_phb_iospace() routine plus appropriate
locking).

Interestingly, this makes the two arms of the if statement in
get_bus_io_range do almost exactly the same thing; that function could
now be simplified in a further patch.

This patch fixes a couple of missing dependencies in
arch/powerpc/boot/Makefile.  First, it ensures that the zlib.h header
is linked in before attempting to build gunzip_util.o, as it is,
building gunzip_util.o usually works, but not always depending on make
order.

Second, it makes the final images which are built using a dts
dependent on that dts, so the image will be correctly rebuilt if the
dts changes.  This in turn requires fixing the definition of the dts
variable.  CONFIG_DEVICE_TREE from Kconfig will have quotes around it,
which don't matter when passing the variable to a shell, but which
need to be removed when incorporating it into a filename for make's
use.

32-bit powerpc uses a PTE_FMT macro to handle printk() formatting of
PTE entries (which can vary in type and size).  Apparently there was a
good reason for it once, but with current compilers it's simpler just
to workaround the variation with a cast in the printk() itself
(there's only one use).

This allows "hotplugging" of CPUs on G5 machines.  CPUs that are
disabled are put into an idle loop with the decrementer frequency set
to minimum.  To wake them up again we kick them just like when bringing
them up.  To stop those CPUs from messing with any global state we stop
them from entering the timer interrupt.

When data symbols are not present in kernel image, user needs to add

==============================
User needs add "." to "do_fork"

kp.symbol_name = ".do_fork";
============================
