[PATCH v2 Resend 1/2] ARM: EXYNOS: Update secondary boot addr for secure mode

[PATCH v2 Resend 1/2] ARM: EXYNOS: Update secondary boot addr for secure mode

[Sachin Kamat]

Almost all Exynos-series of SoCs that run in secure mode don't need
additional offset for every CPU, with Exynos4412 being the only
exception.

Tested on Origen-Quad (Exynos4412) and Arndale-Octa (Exynos5420).

While at it, fix the coding style (space around *).

Fixes ODROID-XU (Exynos5410) as well - thought it had been a prereq to
applying the 5410 patches...

Andreas, thanks for your test :-)

Sachin, How about exynos4210, 5250, 5260 and 5440?...
I need to check again, honestly I don't remember all of Exynos SoCs' 
different things ;-) Then will apply into fixes for 3.16.

Thanks,

Exynos4210 doesn't use secure firmware, at least on any board supported
in mainline. Not sure about those Exynos5 models, but the only boards
supported in mainline with firmware node in DT are based on Exynos4412
or Exynos5410.
