SMC calls vary greatly in how they are handled. The only thing that's generic is issuing the SMC call. All the setup and what arguments are required are completely different from SoC to SoC.
For example, some SoCs require arguments passed via memory. Others like OMAP its via registers. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
