Subject: [PATCH v2 0/6] ARM: rockchip: add smp functionality

This series enables the use of the additional cores on Rockchip
Cortex-A9 SoCs.

To achieve this, add the scu, the needed sram and power-management-unit.

changes since v1:
- add reserved block feature for mmio-sram, to not use two logical
  sram nodes
- the sram content is kept intact while the device is running, so
  copying the trampoline is only needed once

Heiko Stuebner (6):
  misc: sram: fix error path in sram_probe
  misc: sram: add ability to mark sram sections as reserved
  arm: rockchip: add snoop-control-unit
  arm: rockchip: add sram dt nodes and documentation for the smp part
  arm: rockchip: add power-management-unit dt node
  arm: rockchip: add smp bringup code
