[PATCH v3 0/6] ARM: EXYNOS: Add secure firmware support

[Tomasz Figa]

Some Exynos-based boards are running with secure firmware running in
TrustZone secure world, which changes the way some things have to be
initialized.

This series adds support for specifying firmware operations, implements
some firmware operations for Exynos secure firmware and adds a method of
enabling secure firmware operations on Exynos-based boards through board
file and device tree.

Changes since v2
( http://thread.gmane.org/gmane.linux.kernel.samsung-soc/12848 )
  - Made Exynos firmware binding require address
  - Minor style fixes

Changes since v1
( http://thread.gmane.org/gmane.linux.kernel.samsung-soc/12583/focus=12820 )
  - Changed return types of all operations to int
  - Defined all operations to return 0 on success, -ENOSYS when not
    implemented or appropriate error code on error

    operations
