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
