[U-Boot] [PATCH v3 00/11] ARMv7: PSCI: add PSCI v1.0 support

[macro.wave.z at gmail.com]

From: Hongbo Zhang <hongbo.zhang at nxp.com>

Previous v2 patch set was sent out for a long time but got no comments, this
time I send a v3 with minor updates and with more people in list, they are
contributors for Linux kernel PSCI codes.

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.
