[Linaro-acpi] SCI useful pointers

Hi Yi,

I prepared couple of pointers for you. - wiki page about APEI which use SCI mechanism for x86: https://wiki.linaro.org/LEG/Engineering/Kernel/ACPI/EINJ

- since there is no SCI for ARM we added to our acpi git tree commit which simulates SCI behaviour for test purposes: ACPI: Enable SCI_EMULATE to manually simulate physical hotplug testing You can find SCI emulation usage example on wiki page above.

- JIRA card description which gives brief description of GPIO signalled events idea for ACPI Hardware Reduced profile: https://cards.linaro.org/browse/CARD-756

Let me know if you will have any questions.
