Upgrading PSCI from v1.0 to v1.1

[MarekBykowski]

Hi,

I'm doing the work of upgrading PSCI to v1.1.

It is clear for me from that the v1.1 introduces SYSTEM_RESET2, MEM_PROTECT (and MEM_PROTECT_CHECK_RANGE) and I have to port/implement them. However I have trouble determining what the following delta is (referred to from http://infocenter.arm.com/help/topic/com.arm.doc.den0022d/Power_State_Coordination_Interface_PDD_v1_1_DEN0022D.pdf):

• Added additional details on registers that should be initialized when EL2 is not used
• Updated save restore language to make it more generic. See section6.8.
• Removed big.LITTLE migration language
• Added flexibility in encoding of power state parameters in statisticscalls
• Added clarification to GICv3 ITS save and restore

I cannot find any specific commits integrating the points above on "integration" branch. Should I just go ahead and not really bother with it.

Thanks, Marek

This is more clarification in the specification and many of them were already catered for in the implementation. I don't think you should worry about them.
