Hi Claudius,

The only register used in that function is gpr10, which is used to store the flag. So naming it after this makes sense.
I think the old name had a reason: The _value_ for bmode is stored in GPR9 if this function returns true. But I agree that the name is a bit confusing.
Maybe it would make more sense to call it imx6_is_bmode_from_gpr, without any specific register name and add a comment documenting that if bit (GPR10 & IMX6_SRC_GPR10_BMODE) is set, the bmode value is stored in GPR9?
