I don't know who "we" is, but you don;t have my ACK for this, and as
long as it's not even correct youwill not get it.

We can simply chose NOT to use this.

There is zero need to copy bugs or incorrect code from Linux.
Instead, someone should send patches to fix this in Linux, too (or
better to kill it alltogether).

Russel? In case you are referring to RMK you better let not see him
that you misspell his name. He is pretty allergic on this.
Anyway: RMK has zero votes on U-Boot code.

But I insist.
My preference is to get rid of this, but at least fix the bugs before
we use it.
