Merge tag 'armsoc-cleanup' into test-merge
ARM: SoC cleanups for v4.2 A relatively small setup of cleanups this time around, and similar to last time the bulk of it is removal of legacy board support: - OMAP: removal of legacy (non-DT) booting for several platforms - i.MX: remove some legacy board files Conflicts: None # gpg: Signature made Wed Jun 24 21:32:09 2015 PDT using RSA key ID D3FBC665 # gpg: Good signature from "Kevin Hilman <khilman@deeprootsystems.com>" # gpg: aka "Kevin Hilman <khilman@linaro.org>" # gpg: aka "Kevin Hilman <khilman@kernel.org>"
