Actually, I'd be tempted to squash all of patches 2-5 together. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

To support LP1, we need to hook sleep_core function. That will turn off MMU and jump to the IRAM to execute the rest of LP1 suspend function. And we need the the LP1 IRAM addr to backup the original content and replace it with LP1 low level support code.
