CONFIG_VIDEO_HANTRO has the following dependency chain:
Depends on: STAGING [=y] && STAGING_MEDIA [=y] && MEDIA_SUPPORT [=y] && (ARCH_MXC [=n] || ARCH_ROCKCHIP [=n] || COMPILE_TEST [=n]) && VIDEO_DEV [=y] && VIDEO_V4L2 [=y]

Maybe a better fix is to add ARCH_AT91 in the list of supported archs.
Emil, can you shed some light on this?
