[U-Boot] [RFC] [PATCH 0/8] a83t: Add initial PSCI / SMP support

[tpearson at raptorengineering.com]

This is an intial series aimed at getting non-secure mode for virtualization to work on the Allwinner A83t devices. 
This series adds PSCI support along with a few other other low-level initialization routines and boots the mainline
kernel enough to detect 8 started SMP cores / threads.  Unfortunately the mainline kernel appears to have other issues
with timers so this could not be tested further, however it is hoped that with proper u-boot PSCI support the kernel
developers will be able to work on SMP support for these SoCs.

This is a first rough draft; in particular the WFI PSCI state has not been updated for the new device.  Comments on
the overall approach are welcome!
