[U-Boot] [RFC PATCH 0/8] Allwinner A83T PSCI SMP support

[Icenowy Zheng]

This is an experimental support for the PSCI SMP bringup of the first
cluster of Allwinner A83T SoC.

It's based on some code by Timothy Pearson for A83T (already quite old)
and Chen-Yu Tsai (which are originally for A80).

In order to ensure the Linux kernel to work properly in SMP environment,
some GIC workarounds implemented in [1] is needed.

Chen-Yu Tsai (2):
  sunxi: Add CPUCFG register definitions for A80/A83T SoCs
  sunxi: Add basic PSCI implementation for multi-cluster SoCs

Icenowy Zheng (4):
  sunxi: add configuration of secure SRAM for A83T
  sunxi: add SUNXI_R_CPUCFG_BASE for A83T SoC
  sunxi: add multi-cluster CPU PRCM register definition
  sunxi: enable PSCI for A83T SoC

  sun8i: Add TZPC setup for A83T
  sun8i: Add a macro to read the silicon revision
