I'm not so sure. As mentioned, this was used in really old kernel versions only. I remember it for the Power archtecture, where only the pre-devicetree kernel versions (i. e. 2.4.x) used this. OK, I know of a number of projeects which are still using such old kernbel versions, but these are also using ancient U-Boot versions. I don't think we have to keep support for ancient kernels in current U-Boot. Eventually we may drop it.
