The Allwinner SID device holds a 16-bit SoC identifier, which we already use in our code. Export this number through the generic SMCCC SOCID interface, to allow an architectural identification of an Allwinner SoC. This enables access to this information from non-secure world, simplifies generic drivers (ACPI comes to mind), and gives easy and precise access to the SoC ID from userland in OSes like Linux.
