I'm holding on this series...any opinions on this?

If there is no objection on this, let me try to send this out...

Thanks.

Best regards,

[PATCH v4 0/5] ARM: EXYNOS: Add secure firmware support

2012-11-22 Thread 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.

Depends on:
  - ARM: EXYNOS: Add support for secondary CPU bring-up on Exynos4412

Changes since v3
( http://thread.gmane.org/gmane.linux.kernel.samsung-soc/13442 )
