From 2270e6d30bb6601ffd42e9d972442df0499ad547 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Wed, 20 Feb 2013 13:59:13 +0000 Subject: metag: copy devicetree to non-init memory Make a copy of the device tree blob in non-init memory. It is required when using built-in device tree files that the platform code copies the blob to non-init memory prior to calling unflatten_device_tree(), otherwise the strings that the device tree refer to will get poisoned and potentially reused, breaking later reading of the device tree post-init (such as compatible matching in modules, debugfs, and the procfs interface).
