v4 changes: - since there is already PSCI v0.2 function IDs definition merged in 5a07abb, I give up my previous patches 1/11 and 2/11, and move previous 7/11 "ARMv7: PSCI: add PSCI v1.0 functions skeleton" as current first one 1/9 - accept Andre's comment to add the missed "arm,psci-0,2" into compatible string
v3 changes: - patch 3/11, re-init the stack pointer to address like start of page instead of page end, because for ARM push operation, the stack pointer is encreased before storing data. - patch 10/11, delete the previous un-implemented cpu_suspend function for ls1 platform, because there is default blank functions for all those are not implemented in specific platform.
v2 changes: - re-organize psci_cpu_on_common, this code should be called by each platform's psci_cpu_on, should not be a function calling each psci_cpu_on, all related functions are updated due to this change - update some registers usage, e.g. if r10 is used without push/pop, u-boot cannot launch rt-kernel - update some comments to be clearer, re-organize all patches for easier review - add patch to check already_on or on_pending for LS102XA
This patch set contains two parts: ARMv7 PSCI common framework: fix some issues and add v1.0 support NXP (was Freescale) LS102XA: codes enhancement and add v1.0 implementation And this patch set was initially created by Dongsheng Wang.
