For the secure firmware, this is indeed required for U2/U3, otherwise the system crashes in weird ways during early boot. If this entry also makes sense for ODROID-X, I'm surprised it was not there already, does it boot without it? As for the watchdog, g2d and fimc, is there really any Exynos4412 configuration where such components are not available? Sorry if that is a silly question - just wondering why we wouldn't enable these in exynos4412.dtsi.

It probably does, but certain things fail, such as secondary CPU bring-up. > > As for the watchdog, g2d and fimc, is there really any Exynos4412 > configuration where such components are not available? > Sorry if that is a silly question - just wondering why we wouldn't > enable these in exynos4412.dtsi. I believe they should all be enabled at highest possible level, as they don't have any board-specific hardware dependencies. Probably even in exynos4.dtsi for some of them (watchdog likely).

This patch adds support for common hardware modules available on all Exynos4412-based Odroid boards, which already have complete support in mainline kernel. This includes secure firmware calls, watchdog, g2d and fimc (mem2mem) multimedia accelerators.
