Subject[RFC PATCH 2/4] ARM: align cpu_method_of_table naming
Date
From: Rob Herring <robh@kernel.org>

The cpu_method_of_table is the oddball of the various OF linker sections.
In preparation to have common linker section definitions, align the
cpu_method_of_table with the other definitions for the naming and ending
with a blank struct.
