Based linux-sunxi#sunxi commit d854c4de2f57 "arm: Handle .gnu.hash section in
ldscripts" vs v2014.01.
This has been stripped back for mainlining and supports only sun7i booting via
FEL mode. These changes are not useful by themselves but are split out to make
the patch sizes more manageable.
As well as the following signed-off-by the sunxi branch shows commits to these
