This patch adds a list of function IDs that fall under the standard
SMC range as defined in
http://infocenter.arm.com/help/topic/com.arm.doc.den0060a/DEN0060A_ARM_MM_Interface_Specification.pdf.
SMCs associated with Management Mode are in the range 0xC4000040 -
0xC400005f (64 bit) and 0x84000040 - 0x8400005f (32 bit).
The function(s) available to the normal world:
1. Request services from the secure MM environment using MM_COMMUNICATE.
It also defines MM return codes.

SVCs are in the range 0xC4000060 - 0xC400007f.
The functions available to the secure MM partition:
1. Signal completion of MM event handling.
2. Set/Get memory attributes for a memory region at runtime.
3. Get version number of secure partition manager.
Also, it defines memory attributes required for set/get operations.

I should have spotted this earlier but the following define is not
spec. compliant. It says:

but should be

Supreeth. Could you please submit a patch to rectify this?

I can do that.
However, "-4" is missing in the specification. Is there a chance to rectify specification to add "-4", so that I can do both the defines.
Thanks,

To indicate what error? Anyways, lets take this offline. For the time being, the
code should match the spec.
