Subject: [U-Boot] [PATCH 1/2] [v2] fdt: add support for the ePAPR "phandle" property
Date: Fri, 6 May 2011 14:56:37 -0500	[thread overview]
Message-ID: <1304711797-10549-1-git-send-email-timur@freescale.com> (raw)

The ePAPR specification says that phandle properties should be called
"phandle", and not "linux,phandle".  To facilitate the migration from
"linux,phandle" to "phandle", we update some functions to support both
properties.

Upstream libfdt already has the ePAPR changes, so would someone please pull
in those changes?
