entry to use
The correct #address-cells was still used for the actual translation,
so the impact is only a possibility of choosing the wrong range entry
or failing to find any match. Most common cases were not affected.

This patch adds a new generic device tree processing function that retrieves
virtual reg addresses from the device tree to the bootwrapper code. It also
updates the bootwrapper code to use the new function.
dt_get_virtual_reg() retrieves the virtual reg addresses from the
"virtual-reg" property. If the property can't be found, it uses the "reg"
property and walks the tree to translate it to absolute addresses.

Add the ability to set the mac address given the alias for the device.
Removes the need for having a linux,network-index property.

This allows callers to set addresses one at a time when that would be more
convenient.

Some firmwares (such as PlanetCore) only provide a base MAC address, and
expect the kernel to set certain bits to generate the addresses for the
other ports. As such, MAC addresses are generated that may not correspond
to actual hardware.

This allows booting on legacy, non-device-tree aware versions of U-boot.
It also fixes up the hardware to match the PCI and chipselect information
in the device tree, as u-boot is inconsistent in setting these up
correctly (or at all).

This can be used rather than doing a simple strcmp, which will fail to
handle multiple compatible entries.

1. The check whether ranges fits in the buffer was using elements rather
than bytes.
2. Empty ranges were not properly treated as transparent, and missing
ranges were treated as transparent.
3. The loop terminated when translating from the root rather than to. Once
bug #2 was fixed, it failed due to a missing ranges in the root node.
4. In decoding the ranges property, the #size-cells used was that of
the parent, not the child.

dt_xlate_reg() looks up the 'reg' property in the specified node
to get the address and size to translate. Add dt_xlate_addr()
which is passed in the address and size to translate.

This fixes a few bugs in how dt_xlate_reg() handles address arrays:
1. copy_val() was copying into the wrong end of the array, resulting
in random stack garbage at the other end.
2. dt_xlate_reg() was getting the result from the wrong end of the array.
3. add_reg() and sub_reg() were treating the arrays as
little-endian rather than big-endian.
4. add_reg() only returned an error on a carry out of the entire
array, rather than out of the naddr portion.
5. The requested reg resource was checked to see if it exceeded
the size of the reg property, but not to see if it exceeded the
size of the buffer.

dt_xlate_reg() uses the ranges properties of a node's parentage to find
the absolute physical address of the node's registers.
The ns16550 driver uses this when no virtual-reg property is found.

This patch adds a library of useful device tree manipulation functions
to the zImage library, for use by platform code. These functions are
based on the hooks already in dt_ops, so they're not dependent on a
particular device tree implementation. This patch also slightly
streamlines the code in main.c using these new functions.
This is a consolidation of my work in this area with Scott Wood's
patches to a very similar end.
