powerpc/bootwrapper: Use the child-bus #address-cells to decide which range entry to use

2008-12-21T03:21:17+00:00

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.

[POWERPC] Add bootwrapper function to get virtual reg from the device tree.

2008-04-17T06:01:37+00:00

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.

[POWERPC] bootwrapper: Add find_node_by_alias and dt_fixup_mac_address_by_alias

2008-01-24T01:32:44+00:00

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

[POWERPC] bootwrapper: Factor out dt_set_mac_address()

2007-10-03T01:48:43+00:00

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

[POWERPC] bootwrapper: Only print MAC addresses when the node is actually present

2007-09-13T15:33:23+00:00

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.

[POWERPC] bootwrapper: Add PowerQUICC II (82xx with CPM) cuboot support

2007-08-22T05:37:09+00:00

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).

[POWERPC] bootwrapper: Add dt_is_compatible()

2007-08-22T05:21:48+00:00

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

[POWERPC] bootwrapper: dt_xlate_range() bugfixes

2007-08-22T05:21:48+00:00

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.

[POWERPC] bootwrapper: Set timebase_period_ns from dt_fixup_cpu_clocks

2007-08-22T05:21:47+00:00

This lets udelay() work properly on platforms which use dt_fixup_cpu_clocks.

[POWERPC] Add dt_xlate_addr() to bootwrapper

2007-04-30T01:02:05+00:00

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.
