In some discussion on the u-boot dev list it became clear that having
aliases in the device tree might be useful as a common way to deal
with finding specific nodes that need fixing up by the firmware.
This problem also exists in the kernel bootwrappers.
The common example is how to associate a given MAC address with the
proper ethernet node. In u-boot an explicit path is hard coded into
the u-boot build for each ethernet device. In the bootwrapper we use
"linux,network-index = <N>" in the given ethernet node.
One common solution would be having a top level aliases like the pmac
tree's have:
aliases {
enet0 = "...";
enet1 = "...";
pci0 = "...";
pci1 = "...";
};
I wanted to see what people think of this idea and about trying to
use common names for the aliases? If nothing else I believe we will
look at doing this on the FSL boards/parts.
