ARM: rockchip: select ARMv7 compiler flags for platsmp.o When compiling for multiplatform for both ARMv6 and ARMv7, the default compiler flags are for ARMv6, and the following cpu-hotplug change will fail with: /tmp/ccSFxfmI.s:68: Error: selected processor does not support ARM mode `isb ' /tmp/ccSFxfmI.s:74: Error: selected processor does not support ARM mode `isb ' /tmp/ccSFxfmI.s:75: Error: selected processor does not support ARM mode `dsb ' Fix this in a similar manner as in commit 9f0affcf3e21 "ARM: mvebu: Fix pmsu compilation when ARMv6 is selected", by specifying ARMv7 flags for platsmp.o.

arm: add basic support for Rockchip RK3066a boards This adds a generic devicetree board file and a dtsi for boards based on the RK3066a SoCs from Rockchip. Apart from the generic parts (gic, clocks, pinctrl) the only components currently supported are the timers, uarts and mmc ports (all DesignWare- based).

ARM: rockchip: add smp bringup code This adds the necessary smp-operations and startup code to use additional cores on Rockchip SoCs. We currently hog the power management unit in the smp code, as it is necessary to control the power to the cpu core and nothing else is currently using it, so a generic implementation can be done later.
