This patchset aims to support the legacy SCPI firmware implementation that was delivered as early technology preview for the JUNO platform. Finally a stable, maintained and public implementation for the SCPI protocol has been upstreamed part of the JUNO support and it is the recommended way of implementing SCP communication on ARMv8 platforms. The Amlogic GXBB platform is using this legacy protocol, as the RK3368 & RK3399 platforms. This patchset add support for the legacy protocol in the arm_scpi.c file, avoiding code duplication. Last RFC discution tread can be found at : https://lkml.org/lkml/2016/8/9/210 The first patch is here to provide vendor commands on the official SCPI protocol, it can be delayed to another patchset. Patches 8 & 9 are only here to demo how Rockchip support could be implemented, these patches should be delayed to a rockchip specific patchset. The last patch depends on the "Platform MHU" dtsi patch.
