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.

This is a continuation of the patch series by Kyungmin Park:
[PATCH v5 1/2] ARM: Make a compile firmware conditionally
http://thread.gmane.org/gmane.linux.ports.arm.kernel/183607
[PATCH v5 2/2] ARM: EXYNOS: SMC instruction (aka firmware) support
http://thread.gmane.org/gmane.linux.ports.arm.kernel/183608/focus=184109

Tomasz Figa (5):
  ARM: EXYNOS: Add IO mapping for non-secure SYSRAM.
  ARM: Add interface for registering and calling firmware-specific
    operations
  ARM: EXYNOS: Add support for secure monitor calls
  ARM: EXYNOS: Add support for Exynos secure firmware
  ARM: EXYNOS: Add secure firmware support to secondary CPU bring-up

Any further comments for this series? Maybe we could merge it for 3.7?

Hi Arnd, Olof,
Can you merge it for 3.7? If exynos implementation still has issues,
it's okay only merge firmware implementation.

Can you give your opinions?

Hi,

There are still a few open questions to resolve on this before I think it
can be merged. And it doesn't make much sense to merge the infrastructure
without at least the first user of it.
