Not any good reason. I'm aware of historic porting issue and the missed/hidden need for early init for some time services.

1st attempts to do really early init (like 7 years back) were messed as not all kernel services used to be available when the time early time init functions happened.

It was hidden because u-boot had already turned on the same clock the kernel level driver used. So there was no failure (until the kernel used something else).

Recurring breaks & fixes happened to out of trees as owners changed. The mainline never enabled driver till recently.
