of_property_read_bool() if anything. But I didn't want to do that kind
of transformation - just a pure "move this code out and fix the
indentation" with the minor edits needed to hook it back up where it
came from.

Eh, no, it's used in several other places in the driver. I kind of hope
gcc is smart enough to see that in the !PPC32 case it is a static,
never-assigned-to, never-escapes variable so all the "if (soft_uart)"
branches go away, but that's not really very important.
