From bc1e0dd947875eba7d526e1551623f0c1458b565 Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Fri, 10 Feb 2017 08:23:23 -0600 Subject: [PATCH] arm: omap5: Fix generation of reserved-memory DT node When the node 'reserved-memory' is not defined in the DT we fail to add needed properties. We also fail to move 'offs' to point to the new node. Fix these here. Signed-off-by: Andrew F.
