Where in the RM can you get these values?

0x4 is stream ID, any value between 0-31, uboot will use this value to
config stream ID for bus master by scfw API

0x7f80 means tire some bit to high before pass to smmu by hardware.
I don't think signal defination can be found at public documents.

static int arm_smmu_of_xlate(struct device *dev,
                             const struct of_phandle_args *args)
{
        u32 mask, fwid = 0;

        if (args->args_count > 0)
                fwid |= FIELD_PREP(ARM_SMMU_SMR_ID, args->args[0]);

        if (args->args_count > 1)
                fwid |= FIELD_PREP(ARM_SMMU_SMR_MASK, args->args[1]);
}
