Both Tegra and i.MX provide ac97 operations, which can only exist once in the kernel. They can both be built as loadable modules (only one of them needs to be loaded anyway), but we have to disallow enabling them both as built-in.
It's just the ac97 drivers that are mutually exclusive. I'm not sure whether it makes sense to make the whole platforms mutually exclusive for this.
Also this is not limited to tegra and imx. As more platforms are converted to multiplatform ARM the same issue will pop up for other platforms as well. I don't think your solution will scale really well for multiple platforms. The best solution would of course be to make AC97 work properly with multiple AC97 drivers. But maybe we can get away with a 'choice' Kconfig entry which allows you to select which platforms AC97 driver you want to build.
