Subject: ARM: EXYNOS: Update secondary boot addr for secure mode
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=35e75645f16c86918f26df1bfc2c24ad8ebb5a17;hp=8bf13a4346996b5a53d5f0c64b0914693c818fc2;p=deliverable%2Flinux.git

ARM: EXYNOS: Update secondary boot addr for secure mode

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 *).
