Subject: [PATCH 3.4 150/172] powerpc/mpc85xx: Add ranges to etsec2 nodes

From: Scott Wood <scottwood@...escale.com>

3.4.108-rc1 review patch.  If anyone has any objections, please let me know.

------------------


commit bb344ca5b90df62b1a3b7a35c6a9d00b306a170d upstream.

Commit 746c9e9f92dd "of/base: Fix PowerPC address parsing hack" limited
the applicability of the workaround whereby a missing ranges is treated
as an empty ranges.  This workaround was hiding a bug in the etsec2
device tree nodes, which have children with reg, but did not have
ranges.
