Log: Enable pl310 coherent operation in platform init for Armada 38x Updating PL310 sotfware context sc_io_coherent field in platform_pl310_init() routine for Armada 38x helps to avoid using 'arm,io-coherent' property, which is by default not present in the device tree node in Linux. This way another step for DT unification between two operating systems is done. The improvemnt will also work after enabling PLATFORM for Marvell ARMv7 SoCs.
