[RFC 0/1] PowerPC legacy serial console / device tree

Proposing to use the 'cell-index' property to map device tree serial
nodes to legacy serial port number.  For example this allows the
device to explicity specify which serial device to use for ttyS0.

The basic idea is outlined in the following patch.

If this approach seems reasonable I would follow up with additional
patches for Documentation/devicetree/ bindings and
Documentation/powerpc/.
